static long	H5PTcreate_fl(long loc_id, BytePointer dset_name, long dtype_id, long chunk_size, int compression) Deprecated. This function was deprecated in favor of the function H5PTcreate(). \details The H5PTcreate_fl() creates and opens a packet table named \p dset_name attached to the object specified by the identifier \p loc_id. It should be closed with H5PTclose(). The datatype, \p dtype_id, may specify any datatype, including variable-length data. If \p dtype_id specifies a compound datatype, one or more fields in that compound type may be variable-length. \p chunk_size is the size in number of table entries per chunk. Packet table datasets use HDF5 chunked storage to allow them to grow. This value allows the user to set the size of a chunk. The chunk size affects performance. \p compression is the compression level, a value of 0 through 9. Level 0 is faster but offers the least compression; level 9 is slower but offers maximum compression. A setting of -1 indicates that no compression is desired.

H5AC__CURR_CACHE_CONFIG_VERSION

public static final int H5AC__CURR_CACHE_CONFIG_VERSION

structure H5AC_cache_config_t H5AC_cache_config_t is a public structure intended for use in public APIs. At least in its initial incarnation, it is basically a copy of struct H5C_auto_size_ctl_t, minus the report_fcn field, and plus the dirty_bytes_threshold field. The report_fcn field is omitted, as including it would require us to make H5C_t structure public. The dirty_bytes_threshold field does not appear in H5C_auto_size_ctl_t, as synchronization between caches on different processes is handled at the H5AC level, not at the level of H5C. Note however that there is considerable interaction between this value and the other fields in this structure. Similarly, the open_trace_file, close_trace_file, and trace_file_name fields do not appear in H5C_auto_size_ctl_t, as most trace file issues are handled at the H5AC level. The one exception is storage of the pointer to the trace file, which is handled by H5C. The structure is in H5ACpublic.h as we may wish to allow different configuration options for metadata and raw data caches. The fields of the structure are discussed individually below: version: Integer field containing the version number of this version of the H5AC_cache_config_t structure. Any instance of H5AC_cache_config_t passed to the cache must have a known version number, or an error will be flagged. rpt_fcn_enabled: Boolean field used to enable and disable the default reporting function. This function is invoked every time the automatic cache resize code is run, and reports on its activities. This is a debugging function, and should normally be turned off. open_trace_file: Boolean field indicating whether the trace_file_name field should be used to open a trace file for the cache. *** DEPRECATED *** Use H5Fstart/stop logging functions instead The trace file is a debugging feature that allow the capture of top level metadata cache requests for purposes of debugging and/or optimization. This field should normally be set to FALSE, as trace file collection imposes considerable overhead. This field should only be set to TRUE when the trace_file_name contains the full path of the desired trace file, and either there is no open trace file on the cache, or the close_trace_file field is also TRUE. close_trace_file: Boolean field indicating whether the current trace file (if any) should be closed. *** DEPRECATED *** Use H5Fstart/stop logging functions instead See the above comments on the open_trace_file field. This field should be set to FALSE unless there is an open trace file on the cache that you wish to close. trace_file_name: Full path of the trace file to be opened if the open_trace_file field is TRUE. *** DEPRECATED *** Use H5Fstart/stop logging functions instead In the parallel case, an ascii representation of the mpi rank of the process will be appended to the file name to yield a unique trace file name for each process. The length of the path must not exceed H5AC__MAX_TRACE_FILE_NAME_LEN characters. evictions_enabled: Boolean field used to either report the current evictions enabled status of the cache, or to set the cache's evictions enabled status. In general, the metadata cache should always be allowed to evict entries. However, in some cases it is advantageous to disable evictions briefly, and thereby postpone metadata writes. However, this must be done with care, as the cache can grow quickly. If you do this, re-enable evictions as soon as possible and monitor cache size. At present, evictions can only be disabled if automatic cache resizing is also disabled (that is, ( incr_mode == H5C_incr__off ) && ( decr_mode == H5C_decr__off )). There is no logical reason why this should be so, but it simplifies implementation and testing, and I can't think of any reason why it would be desirable. If you can think of one, I'll revisit the issue. set_initial_size: Boolean flag indicating whether the size of the initial size of the cache is to be set to the value given in the initial_size field. If set_initial_size is FALSE, the initial_size field is ignored. initial_size: If enabled, this field contain the size the cache is to be set to upon receipt of this structure. Needless to say, initial_size must lie in the closed interval [min_size, max_size]. min_clean_fraction: double in the range 0 to 1 indicating the fraction of the cache that is to be kept clean. This field is only used in parallel mode. Typical values are 0.1 to 0.5. max_size: Maximum size to which the cache can be adjusted. The supplied value must fall in the closed interval [MIN_MAX_CACHE_SIZE, MAX_MAX_CACHE_SIZE]. Also, max_size must be greater than or equal to min_size. min_size: Minimum size to which the cache can be adjusted. The supplied value must fall in the closed interval [H5C__MIN_MAX_CACHE_SIZE, H5C__MAX_MAX_CACHE_SIZE]. Also, min_size must be less than or equal to max_size. epoch_length: Number of accesses on the cache over which to collect hit rate stats before running the automatic cache resize code, if it is enabled. At the end of an epoch, we discard prior hit rate data and start collecting afresh. The epoch_length must lie in the closed interval [H5C__MIN_AR_EPOCH_LENGTH, H5C__MAX_AR_EPOCH_LENGTH]. Cache size increase control fields: incr_mode: Instance of the H5C_cache_incr_mode enumerated type whose value indicates how we determine whether the cache size should be increased. At present there are two possible values: H5C_incr__off: Don't attempt to increase the size of the cache automatically. When this increment mode is selected, the remaining fields in the cache size increase section ar ignored. H5C_incr__threshold: Attempt to increase the size of the cache whenever the average hit rate over the last epoch drops below the value supplied in the lower_hr_threshold field. Note that this attempt will fail if the cache is already at its maximum size, or if the cache is not already using all available space. Note that you must set decr_mode to H5C_incr__off if you disable metadata cache entry evictions. lower_hr_threshold: Lower hit rate threshold. If the increment mode (incr_mode) is H5C_incr__threshold and the hit rate drops below the value supplied in this field in an epoch, increment the cache size by size_increment. Note that cache size may not be incremented above max_size, and that the increment may be further restricted by the max_increment field if it is enabled. When enabled, this field must contain a value in the range [0.0, 1.0]. Depending on the incr_mode selected, it may also have to be less than upper_hr_threshold. increment: Double containing the multiplier used to derive the new cache size from the old if a cache size increment is triggered. The increment must be greater than 1.0, and should not exceed 2.0. The new cache size is obtained my multiplying the current max cache size by the increment, and then clamping to max_size and to stay within the max_increment as necessary. apply_max_increment: Boolean flag indicating whether the max_increment field should be used to limit the maximum cache size increment. max_increment: If enabled by the apply_max_increment field described above, this field contains the maximum number of bytes by which the cache size can be increased in a single re-size. flash_incr_mode: Instance of the H5C_cache_flash_incr_mode enumerated type whose value indicates whether and by which algorithm we should make flash increases in the size of the cache to accommodate insertion of large entries and large increases in the size of a single entry. The addition of the flash increment mode was occasioned by performance problems that appear when a local heap is increased to a size in excess of the current cache size. While the existing re-size code dealt with this eventually, performance was very bad for the remainder of the epoch. At present, there are two possible values for the flash_incr_mode: H5C_flash_incr__off: Don't perform flash increases in the size of the cache. H5C_flash_incr__add_space: Let x be either the size of a newly newly inserted entry, or the number of bytes by which the size of an existing entry has been increased. If x > flash_threshold * current max cache size, increase the current maximum cache size by x * flash_multiple less any free space in the cache, and star a new epoch. For now at least, pay no attention to the maximum increment. In both of the above cases, the flash increment pays no attention to the maximum increment (at least in this first incarnation), but DOES stay within max_size. With a little thought, it should be obvious that the above flash cache size increase algorithm is not sufficient for all circumstances -- for example, suppose the user round robins through (1/flash_threshold) +1 groups, adding one data set to each on each pass. Then all will increase in size at about the same time, requiring the max cache size to at least double to maintain acceptable performance, however the above flash increment algorithm will not be triggered. Hopefully, the add space algorithms detailed above will be sufficient for the performance problems encountered to date. However, we should expect to revisit the issue. flash_multiple: Double containing the multiple described above in the H5C_flash_incr__add_space section of the discussion of the flash_incr_mode section. This field is ignored unless flash_incr_mode is H5C_flash_incr__add_space. flash_threshold: Double containing the factor by which current max cache size is multiplied to obtain the size threshold for the add_space flash increment algorithm. The field is ignored unless flash_incr_mode is H5C_flash_incr__add_space. Cache size decrease control fields: decr_mode: Instance of the H5C_cache_decr_mode enumerated type whose value indicates how we determine whether the cache size should be decreased. At present there are four possibilities. H5C_decr__off: Don't attempt to decrease the size of the cache automatically. When this increment mode is selected, the remaining fields in the cache size decrease section are ignored. H5C_decr__threshold: Attempt to decrease the size of the cache whenever the average hit rate over the last epoch rises above the value supplied in the upper_hr_threshold field. H5C_decr__age_out: At the end of each epoch, search the cache for entries that have not been accessed for at least the number of epochs specified in the epochs_before_eviction field, and evict these entries. Conceptually, the maximum cache size is then decreased to match the new actual cache size. However, this reduction may be modified by the min_size, the max_decrement, and/or the empty_reserve. H5C_decr__age_out_with_threshold: Same as age_out, but we only attempt to reduce the cache size when the hit rate observed over the last epoch exceeds the value provided in the upper_hr_threshold field. Note that you must set decr_mode to H5C_decr__off if you disable metadata cache entry evictions. upper_hr_threshold: Upper hit rate threshold. The use of this field varies according to the current decr_mode: H5C_decr__off or H5C_decr__age_out: The value of this field is ignored. H5C_decr__threshold: If the hit rate exceeds this threshold in any epoch, attempt to decrement the cache size by size_decrement. Note that cache size may not be decremented below min_size. Note also that if the upper_threshold is 1.0, the cache size will never be reduced. H5C_decr__age_out_with_threshold: If the hit rate exceeds this threshold in any epoch, attempt to reduce the cache size by evicting entries that have not been accessed for more than the specified number of epochs. decrement: This field is only used when the decr_mode is H5C_decr__threshold. The field is a double containing the multiplier used to derive the new cache size from the old if a cache size decrement is triggered. The decrement must be in the range 0.0 (in which case the cache will try to contract to its minimum size) to 1.0 (in which case the cache will never shrink). apply_max_decrement: Boolean flag used to determine whether decrements in cache size are to be limited by the max_decrement field. max_decrement: Maximum number of bytes by which the cache size can be decreased in a single re-size. Note that decrements may also be restricted by the min_size of the cache, and (in age out modes) by the empty_reserve field. epochs_before_eviction: Integer field used in H5C_decr__age_out and H5C_decr__age_out_with_threshold decrement modes. This field contains the number of epochs an entry must remain unaccessed before it is evicted in an attempt to reduce the cache size. If applicable, this field must lie in the range [1, H5C__MAX_EPOCH_MARKERS]. apply_empty_reserve: Boolean field controlling whether the empty_reserve field is to be used in computing the new cache size when the decr_mode is H5C_decr__age_out or H5C_decr__age_out_with_threshold. empty_reserve: To avoid a constant racheting down of cache size by small amounts in the H5C_decr__age_out and H5C_decr__age_out_with_threshold modes, this field allows one to require that any cache size reductions leave the specified fraction of unused space in the cache. The value of this field must be in the range [0.0, 1.0]. I would expect typical values to be in the range of 0.01 to 0.1. Parallel Configuration Fields: In PHDF5, all operations that modify metadata must be executed collectively. We used to think that this was enough to ensure consistency across the metadata caches, but since we allow processes to read metadata individually, the order of dirty entries in the LRU list can vary across processes, which can result in inconsistencies between the caches. PHDF5 uses several strategies to prevent such inconsistencies in metadata, all of which use the fact that the same stream of dirty metadata is seen by all processes for purposes of synchronization. This is done by having each process count the number of bytes of dirty metadata generated, and then running a "sync point" whenever this count exceeds a user specified threshold (see dirty_bytes_threshold below). The current metadata write strategy is indicated by the metadata_write_strategy field. The possible values of this field, along with the associated metadata write strategies are discussed below. dirty_bytes_threshold: Threshold of dirty byte creation used to synchronize updates between caches. (See above for outline and motivation.) This value MUST be consistent across all processes accessing the file. This field is ignored unless HDF5 has been compiled for parallel. metadata_write_strategy: Integer field containing a code indicating the desired metadata write strategy. The valid values of this field are enumerated and discussed below: H5AC_METADATA_WRITE_STRATEGY__PROCESS_0_ONLY: When metadata_write_strategy is set to this value, only process zero is allowed to write dirty metadata to disk. All other processes must retain dirty metadata until they are informed at a sync point that the dirty metadata in question has been written to disk. When the sync point is reached (or when there is a user generated flush), process zero flushes sufficient entries to bring it into compliance with its min clean size (or flushes all dirty entries in the case of a user generated flush), broad casts the list of entries just cleaned to all the other processes, and then exits the sync point. Upon receipt of the broadcast, the other processes mark the indicated entries as clean, and leave the sync point as well. H5AC_METADATA_WRITE_STRATEGY__DISTRIBUTED: In the distributed metadata write strategy, process zero still makes the decisions as to what entries should be flushed, but the actual flushes are distributed across the processes in the computation to the extent possible. In this strategy, when a sync point is triggered (either by dirty metadata creation or manual flush), all processes enter a barrier. On the other side of the barrier, process 0 constructs an ordered list of the entries to be flushed, and then broadcasts this list to the caches in all the processes. All processes then scan the list of entries to be flushed, flushing some, and marking the rest as clean. The algorithm for this purpose ensures that each entry in the list is flushed exactly once, and all are marked clean in each cache. Note that in the case of a flush of the cache, no message passing is necessary, as all processes have the same list of dirty entries, and all of these entries must be flushed. Thus in this case it is sufficient for each process to sort its list of dirty entries after leaving the initial barrier, and use this list as if it had been received from process zero. To avoid possible messages from the past/future, all caches must wait until all caches are done before leaving the sync point.

H5open

@Cast(value="herr_t")
public static int H5open()

\ingroup H5 \brief Initializes the HDF5 library

Returns:

\herr_t \details H5open() initializes the HDF5 library. \details When the HDF5 library is used in a C application, the library is automatically initialized when the first HDf5 function call is issued. If one finds that an HDF5 library function is failing inexplicably, H5open() can be called first. It is safe to call H5open() before an application issues any other function calls to the HDF5 library, as there are no damaging side effects in calling it more than once.

H5atclose

public static int H5atclose(H5_atclose_func_t func,
                                                   Pointer ctx)

\ingroup H5 \brief Registers a callback for the library to invoke when it's closing.

Parameters:

func - [in] The function pointer to invoke

ctx - [in] Context to pass to \p func when invoked

Returns:

\herr_t \details H5atclose() registers a callback that the HDF5 library will invoke when closing. The full capabilities of the HDF5 library are available to callbacks invoked through this mechanism, and library shutdown will only begin in earnest when all callbacks have been invoked and have returned. Registered callbacks are invoked in LIFO order, similar to the Standard C 'atexit' routine. For example, if 'func1' is registered, then 'func2', when the library is closing 'func2', will be invoked first, then 'func1'. The \p ctx pointer will be passed to \p func when it's invoked. NULL is allowed for \p ctx. If the HDF5 library is initialized and closed more than once, the \p func callback must be registered within each open/close cycle.

H5close

@Cast(value="herr_t")
public static int H5close()

\ingroup H5 \brief Flushes all data to disk, closes all open objects, and releases memory

Returns:

\herr_t \details H5close() flushes all data to disk, closes all open HDF5 objects, and cleans up all memory used by the HDF5 library. This function is generally called when the application calls exit(), but may be called earlier in the event of an emergency shutdown or out of a desire to free all resources used by the HDF5 library.

H5dont_atexit

@Cast(value="herr_t")
public static int H5dont_atexit()

\ingroup H5 \brief Instructs library not to install atexit() cleanup routine

Returns:

\herr_t \details H5dont_atexit() indicates to the library that an atexit() cleanup routine should not be installed. The major purpose for using this function is in situations where the library is dynamically linked into an application and is un-linked from the application before exit() gets called. In those situations, a routine installed with atexit() would jump to a routine that was no longer in memory, causing errors. \attention In order to be effective, this routine \Emph{must} be called before any other HDF5 function calls, and must be called each time the library is loaded/linked into the application (the first time and after it's been unloaded).

H5garbage_collect

@Cast(value="herr_t")
public static int H5garbage_collect()

\ingroup H5 \brief Garbage collects on all free-lists of all types

Returns:

\herr_t \details H5garbage_collect() walks through all garbage collection routines of the library, freeing any unused memory. It is not required that H5garbage_collect() be called at any particular time; it is only necessary for certain situations where the application has performed actions that cause the library to allocate many objects. The application should call H5garbage_collect() if it eventually releases those objects and wants to reduce the memory used by the library from the peak usage required. \note The library automatically garbage collects all the free lists when the application ends.

                                                                int blk_list_lim)

\ingroup H5 \brief Sets free-list size limits

Parameters:

reg_global_lim - [in] The cumulative limit, in bytes, on memory used for all regular free lists (Default: 1MB)

reg_list_lim - [in] The limit, in bytes, on memory used for each regular free list (Default: 64KB)

arr_global_lim - [in] The cumulative limit, in bytes, on memory used for all array free lists (Default: 4MB)

arr_list_lim - [in] The limit, in bytes, on memory used for each array free list (Default: 256KB)

blk_global_lim - [in] The cumulative limit, in bytes, on memory used for all block free lists and, separately, for all factory free lists (Default: 16MB)

blk_list_lim - [in] The limit, in bytes, on memory used for each block or factory free list (Default: 1MB)

Returns:

\herr_t \details H5set_free_list_limits() sets size limits on all types of free lists. The HDF5 library uses free lists internally to manage memory. The types of free lists used are as follows: \li Regular free lists manage memory for single internal data structures. \li Array free lists manage memory for arrays of internal data structures. \li Block free lists manage memory for arbitrarily-sized blocks of bytes. \li Factory free lists manage memory for fixed-size blocks of bytes. The parameters specify global and per-list limits; for example, \p reg_global_limit and \p reg_list_limit limit the accumulated size of all regular free lists and the size of each individual regular free list, respectively. Therefore, if an application sets a 1Mb limit on each of the global lists, up to 4Mb of total storage might be allocated, 1Mb for each of the regular, array, block, and factory type lists. The settings specified for block free lists are duplicated for factory free lists. Therefore, increasing the global limit on block free lists by x bytes will increase the potential free list memory usage by 2x bytes. Using a value of -1 for a limit means that no limit is set for the specified type of free list.

\ingroup H5 \brief Verifies that HDF5 library versions are consistent

Parameters:

majnum - [in] HDF5 library major version number

minnum - [in] HDF5 library minor version number

relnum - [in] HDF5 library release number

Returns:

\herr_t \details H5check_version() verifies that the version of the HDF5 library with which an application was compiled, as indicated by the passed parameters, matches the version of the HDF5 library against which the application is currently linked. \p majnum is the major version number of the HDF library with which the application was compiled, \p minnum is the minor version number, and \p relnum is the release number. Consider the following example: An official HDF5 release is labelled as follows: HDF5 Release \Code{\.\.\}\n For example, in HDF5 Release 1.8.5: \li 1 is the major version number, \p majnum. \li 8 is the minor version number, \p minnum. \li 5 is the release number, \p relnum. As stated above, H5check_version() first verifies that the version of the HDF5 library with which an application was compiled matches the version of the HDF5 library against which the application is currently linked. If this check fails, H5check_version() causes the application to abort (by means of a standard C abort() call) and prints information that is usually useful for debugging. This precaution is taken to avoid the risks of data corruption or segmentation faults. The most common cause of this failure is that an application was compiled with one version of HDF5 and is dynamically linked with a different version different version. If the above test passes, H5check_version() proceeds to verify the consistency of additional library version information. This is designed to catch source code inconsistencies that do not normally cause failures; if this check reveals an inconsistency, an informational warning is printed but the application is allowed to run.

Parameters:

mem - [in] Buffer to be freed. Can be NULL

Returns:

\herr_t \details H5free_memory() frees the memory that has been allocated by the caller with H5allocate_memory() or by the HDF5 library on behalf of the caller. H5Tget_member_name() provides an example of memory allocation on behalf of the caller: The function returns a buffer containing the name of a compound datatype member. It is the caller’s responsibility to eventually free that buffer with H5free_memory(). \attention It is especially important to use this function to free memory allocated by the library on Windows. The C standard library is implemented in dynamic link libraries (DLLs) known as the C run-time (CRT). Each version of Visual Studio comes with two CRT DLLs (debug and release) and allocating and freeing across DLL boundaries can cause resource leaks and subtle bugs due to heap corruption.\n Only use this function to free memory allocated by the HDF5 Library. It will generally not be safe to use this function to free memory allocated by any other means.\n Even when using this function, it is still best to ensure that all components of a C application are built with the same version of Visual Studio and build (debug or release) and thus linked against the same CRT.

\ingroup H5 \brief Frees memory allocated by the HDF5 library

Parameters:

size - [in] The size in bytes of the buffer to be allocated

clear - [in] Flag whether the new buffer is to be initialized with 0

Returns:

On success, returns pointer to newly allocated buffer or returns NULL if size is 0 (zero).\n Returns NULL on failure. \details H5allocate_memory() allocates a memory buffer of size bytes that will later be freed internally by the HDF5 library. The boolean \p clear parameter specifies whether the buffer should be initialized. If clear is \c TRUE, all bits in the buffer are to be set to 0 (zero); if clear is \c FALSE, the buffer will not be initialized. This function is intended to have the semantics of malloc() and calloc(). However, unlike malloc() and calloc(), which allow for a "special" pointer to be returned instead of NULL, this function always returns NULL on failure or when size is set to 0 (zero). \note At this time, the only intended use for this function is to allocate memory that will be returned to the library as a data buffer from a third-party filter. \attention To avoid heap corruption, allocated memory should be freed using the same library that initially allocated it. In most cases, the HDF5 API uses resources that are allocated and freed either entirely by the user or entirely by the library, so this is not a problem. In rare cases, however, HDF5 API calls will free the memory that the user allocated. This function allows the user to safely allocate this memory.\n It is particularly important to use this function to allocate memory in Microsoft Windows environments. In Windows, the C standard library is implemented in dynamic link libraries (DLLs) known as the C run-time (CRT). Each version of Visual Studio comes with multiple versions of the CRT DLLs (debug, release, et cetera) and allocating and freeing memory across DLL boundaries can cause resource leaks and subtle bugs due to heap corruption.\n Even when using this function, it is best where possible to ensure that all components of a C application are built with the same version of Visual Studio and configuration (Debug or Release), and thus linked against the same CRT.\n Use this function only to allocate memory inside third-party HDF5 filters.

\ingroup H5 \brief Resizes and, if required, re-allocates memory that will later be freed internally by the HDF5 library

Parameters:

mem - [in] Pointer to a buffer to be resized. May be NULL

size - [in] New size of the buffer, in bytes

Returns:

On success, returns pointer to resized or reallocated buffer or returns NULL if size is 0 (zero).\n Returns NULL on failure. \details H5resize_memory() takes a pointer to an existing buffer and resizes the buffer to match the value in \p size. If necessary, the buffer is reallocated. If \p size is 0, the buffer is released. The input buffer must either be NULL or have been allocated by H5allocate_memory() since the input buffer may be freed by the library. For certain behaviors, the pointer \p mem may be passed in as NULL. This function is intended to have the semantics of realloc():

\Code{H5resize_memory(buffer, size)}	Resizes buffer. Returns pointer to resized buffer.
\Code{H5resize_memory(NULL, size)}	Allocates memory using HDF5 Library allocator. Returns pointer to new buffer
\Code{H5resize_memory(buffer, 0)}	Frees memory using HDF5 Library allocator. Returns NULL.
\Code{H5resize_memory(NULL, 0)}	Returns NULL (undefined in C standard).

Unlike realloc(), which allows for a "special pointer to be returned instead of NULL, this function always returns NULL on failure or when size is 0 (zero). \note At this time, the only intended use for this function is to resize or reallocate memory that will be returned to the library (and eventually to the user) as a data buffer from a third-party HDF5 filter. \attention To avoid heap corruption, allocated memory should be freed using the same library that initially allocated it.

Parameters:

name - [out] A buffer for the name associated with the identifier

size - [in] The size of the \p name buffer; usually the size of the name in bytes plus 1 for a NULL terminator

Returns:

ssize_t \details H5Iget_name() retrieves a name for the object identified by \p id. \details Up to size characters of the name are returned in \p name; additional characters, if any, are not returned to the user application. If the length of the name, which determines the required value of \p size, is unknown, a preliminary H5Iget_name() call can be made. The return value of this call will be the size in bytes of the object name. That value, plus 1 for a NULL terminator, is then assigned to size for a second H5Iget_name() call, which will retrieve the actual name. If the object identified by \p id is an attribute, as determined via H5Iget_type(), H5Iget_name() retrieves the name of the object to which that attribute is attached. To retrieve the name of the attribute itself, use H5Aget_name(). If there is no name associated with the object identifier or if the name is NULL, H5Iget_name() returns 0 (zero). \note Note that an object in an HDF5 file may have multiple paths if there are multiple links pointing to it.

Returns:

Returns a non-negative reference count of the object ID after incrementing it if successful; otherwise a negative value is returned. \details H5Iinc_ref() increments the reference count of the object identified by \p id. The reference count for an object ID is attached to the information about an object in memory and has no relation to the number of links to an object on disk. The reference count for a newly created object will be 1. Reference counts for objects may be explicitly modified with this function or with H5Idec_ref(). When an object ID's reference count reaches zero, the object will be closed. Calling an object ID's \c close function decrements the reference count for the ID which normally closes the object, but if the reference count for the ID has been incremented with this function, the object will only be closed when the reference count reaches zero with further calls to H5Idec_ref() or the object ID's \c close function. If the object ID was created by a collective parallel call (such as H5Dcreate(), H5Gopen(), etc.), the reference count should be modified by all the processes which have copies of the ID. Generally this means that group, dataset, attribute, file and named datatype IDs should be modified by all the processes and that all other types of IDs are safe to modify by individual processes. This function is of particular value when an application is maintaining multiple copies of an object ID. The object ID can be incremented when a copy is made. Each copy of the ID can then be safely closed or decremented and the HDF5 object will be closed when the reference count for that that object drops to zero.

Returns a non-negative reference count of the object ID after decrementing it, if successful; otherwise a negative value is returned. \details H5Idec_ref() decrements the reference count of the object identified by \p id. The reference count for an object ID is attached to the information about an object in memory and has no relation to the number of links to an object on disk. The reference count for a newly created object will be 1. Reference counts for objects may be explicitly modified with this function or with H5Iinc_ref(). When an object identifier’s reference count reaches zero, the object will be closed. Calling an object identifier’s \c close function decrements the reference count for the identifier, which normally closes the object, but if the reference count for the identifier has been incremented with H5Iinc_ref(), the object will only be closed when the reference count reaches zero with further calls to this function or the object identifier’s \c close function. If the object ID was created by a collective parallel call (such as H5Dcreate(), H5Gopen(), etc.), the reference count should be modified by all the processes which have copies of the ID. Generally, this means that group, dataset, attribute, file and named datatype IDs should be modified by all the processes and that all other types of IDs are safe to modify by individual processes. This function is of particular value when an application maintains multiple copies of an object ID. The object ID can be incremented when a copy is made. Each copy of the ID can then be safely closed or decremented and the HDF5 object will be closed when the reference count for that object drops to zero.

\ingroup H5IUD \brief Creates and returns a new ID type

Parameters:

hash_size - [in] Minimum hash table size (in entries) used to store IDs for the new type

reserved - [in] Number of reserved IDs for the new type

free_func - [in] Function used to deallocate space for a single ID

Returns:

Returns the type identifier on success, negative on failure. \details H5Iregister_type() allocates space for a new ID type and returns an identifier for it. The \p hash_size parameter indicates the minimum size of the hash table used to store IDs in the new type. The \p reserved parameter indicates the number of IDs in this new type to be reserved. Reserved IDs are valid IDs which are not associated with any storage within the library. The \p free_func parameter is a function pointer to a function which returns an herr_t and accepts a \c void*. The purpose of this function is to deallocate memory for a single ID. It will be called by H5Iclear_type() and H5Idestroy_type() on each ID. This function is NOT called by H5Iremove_verify(). The \c void* will be the same pointer which was passed in to the H5Iregister() function. The \p free_func function should return 0 on success and -1 on failure.

                                                       boolean force)

\ingroup H5IUD \brief Deletes all identifiers of the given type

Parameters:

type - [in] Identifier of identifier type which is to be cleared of identifiers

force - [in] Whether or not to force deletion of all identifiers

Returns:

\herr_t \details H5Iclear_type() deletes all identifiers of the type identified by the argument \p type. The identifier type's free function is first called on all of these identifiers to free their memory, then they are removed from the type. If the \p force flag is set to false, only those identifiers whose reference counts are equal to 1 will be deleted, and all other identifiers will be entirely unchanged. If the force flag is true, all identifiers of this type will be deleted.

H5Idestroy_type

@Cast(value="herr_t")
public static int H5Idestroy_type(@Cast(value="H5I_type_t")
                                                         int type)

\ingroup H5IUD \brief Removes an identifier type and all identifiers within that type

Parameters:

type - [in] Identifier of identifier type which is to be destroyed

Returns:

\herr_t \details H5Idestroy_type deletes an entire identifier type \p type. All identifiers of this type are destroyed and no new identifiers of this type can be registered. The type’s free function is called on all of the identifiers which are deleted by this function, freeing their memory. In addition, all memory used by this type’s hash table is freed. Since the H5I_type_t values of destroyed identifier types are reused when new types are registered, it is a good idea to set the variable holding the value of the destroyed type to #H5I_UNINIT.

H5Iinc_type_ref

public static int H5Iinc_type_ref(@Cast(value="H5I_type_t")
                                  int type)

\ingroup H5IUD \brief Increments the reference count on an ID type

Parameters:

type - [in] The identifier of the type whose reference count is to be incremented

Returns:

Returns the current reference count on success, negative on failure. \details H5Iinc_type_ref() increments the reference count on an ID type. The reference count is used by the library to indicate when an ID type can be destroyed. The type parameter is the identifier for the ID type whose reference count is to be incremented. This identifier must have been created by a call to H5Iregister_type().

H5Idec_type_ref

public static int H5Idec_type_ref(@Cast(value="H5I_type_t")
                                  int type)

\ingroup H5IUD \brief Decrements the reference count on an identifier type

Parameters:

type - [in] The identifier of the type whose reference count is to be decremented

Returns:

Returns the current reference count on success, negative on failure. \details H5Idec_type_ref() decrements the reference count on an identifier type. The reference count is used by the library to indicate when an identifier type can be destroyed. If the reference count reaches zero, this function will destroy it. The type parameter is the identifier for the identifier type whose reference count is to be decremented. This identifier must have been created by a call to H5Iregister_type().

H5Iget_type_ref

public static int H5Iget_type_ref(@Cast(value="H5I_type_t")
                                  int type)

\ingroup H5IUD \brief Retrieves the reference count on an ID type

Parameters:

type - [in] The identifier of the type whose reference count is to be retrieved

Returns:

Returns the current reference count on success, negative on failure. \details H5Iget_type_ref() retrieves the reference count on an ID type. The reference count is used by the library to indicate when an ID type can be destroyed. The type parameter is the identifier for the ID type whose reference count is to be retrieved. This identifier must have been created by a call to H5Iregister_type().

                                Pointer key)

\ingroup H5IUD \brief Finds the memory referred to by an ID within the given ID type such that some criterion is satisfied

Parameters:

type - [in] The identifier of the type to be searched

func - [in] The function defining the search criteria

key - [in] A key for the search function

Returns:

Returns a pointer to the object which satisfies the search function on success, NULL on failure. \details H5Isearch() searches through a given ID type to find an object that satisfies the criteria defined by \p func. If such an object is found, the pointer to the memory containing this object is returned. Otherwise, NULL is returned. To do this, \p func is called on every member of type \p type. The first member to satisfy \p func is returned. The \p type parameter is the identifier for the ID type which is to be searched. This identifier must have been created by a call to H5Iregister_type(). The parameter \p func is a function pointer to a function which takes three parameters. The first parameter is a \c void* and will be a pointer to the object to be tested. This is the same object that was placed in storage using H5Iregister(). The second parameter is a hid_t and is the ID of the object to be tested. The last parameter is a \c void*. This is the \p key parameter and can be used however the user finds helpful, or it can be ignored if it is not needed. \p func returns 0 if the object it is testing does not pass its criteria. A non-zero value should be returned if the object does pass its criteria. H5I_search_func_t is defined in H5Ipublic.h and is shown below. \snippet this H5I_search_func_t_snip The \p key parameter will be passed to the search function as a parameter. It can be used to further define the search at run-time.

\ingroup H5IUD \brief Calls a callback for each member of the identifier type specified

Parameters:

type - [in] The identifier type

op - [in] The callback function

op_data - [in,out] The data for the callback function

Returns:

The last value returned by \p op \details H5Iiterate() calls the callback function \p op for each member of the identifier type \p type. The callback function type for \p op, H5I_iterate_func_t, is defined in H5Ipublic.h as: \snippet this H5I_iterate_func_t_snip \p op takes as parameters the identifier and a pass through of \p op_data, and returns an herr_t. A positive return from op will cause the iteration to stop and H5Iiterate() will return the value returned by \p op. A negative return from \p op will cause the iteration to stop and H5Iiterate() will return failure. A zero return from \p op will allow iteration to continue, as long as there are other identifiers remaining in type.

Parameters:

type - [in] Class of datatype to create

size - [in] Size, in bytes, of the datatype being created

Returns:

\hid_t{datatype} \details H5Tcreate() creates a new datatype of the specified class with the specified number of bytes. This function is used only with the following datatype classes: - #H5T_COMPOUND - #H5T_OPAQUE - #H5T_ENUM - #H5T_STRING Other datatypes, including integer and floating-point datatypes, are typically created by using H5Tcopy() to copy and modify a predefined datatype. When creating a variable-length string datatype, \p size must be #H5T_VARIABLE; see \ref_vlen_strings. When creating a fixed-length string datatype, \p size will be the length of the string in bytes. The length of the string in characters will depend on i the encoding used; see #H5Pset_char_encoding. ENUMs created with this function have a signed native integer base datatype. Use H5Tenum_create() if a different integer base datatype is required. The datatype identifier returned from this function should be released with H5Tclose or resource leaks will result.

Returns:

The \p type_id argument can be either a datatype identifier, a predefined datatype (defined in H5Tpublic.h), or a dataset identifier. If \p type_id is a dataset identifier, this function returns a transient, modifiable datatype which is a copy of the dataset's datatype. The returned datatype identifier should be released with H5Tclose() to prevent resource leaks.

Parameters:

Returns:

\herr_t \details H5Tcommit2() saves a transient datatype as an immutable committed datatype in a file. The datatype specified by \p dtype_id is committed to the file with the name name at the location specified by \p loc_id and with the datatype creation and access property lists \p tcpl_id and \p tapl_id, respectively. \p loc_id may be a file identifier, or a group identifier within that file. \p name may be either an absolute path in the file or a relative path from \p loc_id naming the newly-committed datatype. The link creation property list, \p lcpl_id, governs creation of the link(s) by which the new committed datatype is accessed and the creation of any intermediate groups that may be missing. Once committed, this datatype may be used to define the datatype of any other dataset or attribute in the file. This function will not accept a datatype that cannot actually hold information. This currently includes compound datatypes with no fields and enumerated datatypes with no members. Committed datatypes are sometimes referred to as named datatypes.

name - [in] Name of the datatype to open \tapl_id

Returns:

\hid_t{datatype} \details H5Topen2() opens a committed datatype at the location specified by \p loc_id and returns an identifier for the datatype. \p loc_id is either a file or group identifier. The identifier should eventually be closed by calling H5Tclose() to release resources. The committed datatype is opened with the datatype access property list tapl_id.

\ingroup H5T \brief Commits a transient datatype to a file, creating a newly named datatype, but does not link it into the file structure \fg_loc_id \type_id \tcpl_id \tapl_id

Returns:

\herr_t \details H5Tcommit_anon() commits a transient datatype (not immutable) to a file, turning it into a named datatype with the specified creation and property lists. With default property lists, #H5P_DEFAULT, H5Tcommit_anon() provides similar functionality to that of H5Tcommit(), with the differences described below. #H5P_DEFAULT can be passed in for the datatype creation property list identifier, \p tcpl_id. The datatype access property list identifier, \p tapl_id, is provided for future functionality and is not used at this time. This parameter should always be passed as the value #H5P_DEFAULT. Note that H5Tcommit_anon() does not link this newly-committed datatype into the file. After the H5Tcommit_anon() call, the datatype identifier \p type_id must be linked into the HDF5 file structure with H5Olink() or it will be deleted from the file when the file is closed. The differences between this function and H5Tcommit() are as follows: \li H5Tcommit_anon() explicitly includes property lists, which provides for greater control of the creation process and of the properties of the new named datatype. H5Tcommit() always uses default properties. \li H5Tcommit_anon() neither provides the new named datatype’s name nor links it into the HDF5 file structure; those actions must be performed separately through a call to H5Olink(), which offers greater control over linking. This function will not accept a datatype that cannot actually hold data. This currently includes compound datatypes with no fields and enumerated datatypes with no members.

Returns:

If this function returns a positive value, then the type is committed (that is, it has been committed, perhaps by some other application).

\ingroup H5T \brief Encodes a datatype object description into a binary buffer

Parameters:

obj_id - [in] Identifier of the object to be encoded

buf - [in,out] Buffer for the object to be encoded into.

nalloc - [in,out] IN: The size of the allocated buffer OUT: The size of the buffer needed

Returns:

\herr_t \details H5Tencode() Given datatype identifier, H5Tencode() converts a datatype description into binary form in a buffer. Using this binary form in the buffer, a datatype object can be reconstructed using H5Tdecode() to return a new object handle (\ref hid_t) for this datatype. If the provided buffer is NULL, only the size of buffer needed is returned through \p nalloc. A preliminary H5Tencode() call can be made to find out the size of the buffer needed. This value is returned as \p nalloc. That value can then be assigned to \p nalloc for a second H5Tencode() call, which will retrieve the actual encoded object. If the library finds that \p nalloc is not big enough for the object, it simply returns the size of the buffer needed through \p nalloc without encoding the provided buffer.

\ingroup H5T \brief Flushes all buffers associated with a committed datatype to disk \type_id

Returns:

\herr_t \details H5Tflush() causes all buffers associated with a committed datatype \p type_id to be immediately flushed to disk without removing the data from the cache. HDF5 does not possess full control over buffering. H5Tflush() flushes the internal HDF5 buffers and then asks the operating system (the OS) to flush the system buffers for the open files. After that, the OS is responsible for ensuring that the data is actually flushed to disk.

Returns:

\herr_t \details H5Trefresh() causes all buffers associated with a committed datatype to be cleared and immediately re-loaded with updated contents from disk. This function essentially closes the datatype, evicts all metadata associated with it from the cache, and then reopens the datatype. The reopened datatype is automatically re-registered with the same identifier.

Returns:

\herr_t \details H5Tinsert() adds another member to the compound datatype, specified \p type_id. The new member has a \p name which must be unique within the compound datatype. The \p offset argument defines the start of the member in an instance of the compound datatype, and \p member_id is the datatype identifier of the new member. \note Members of a compound datatype do not have to be atomic datatypes; a compound datatype can have a member which is a compound datatype.

Returns:

\hid_t{variable-length datatype} \details H5Tvlen_create() creates a new one-dimensional array datatype of variable-length (VL) with the base datatype \p base_id. This one-dimensional array often represents a data sequence of the base datatype, such as characters for character sequences or vertex coordinates for polygon lists. The base type specified for the VL datatype can be any HDF5 datatype, including another VL datatype, a compound datatype, or an atomic datatype. When necessary, use H5Tget_super() to determine the base type of the VL datatype. The datatype identifier returned from this function should be released with H5Tclose() or resource leaks will result. Under certain circumstances, H5Dvlen_reclaim() must also be used. \attention H5Tvlen_create() cannot be used to create a variable-length string datatype. H5Tvlen_create() called with a string or character base type creates a variable-length sequence of strings (a variable-length, 1-dimensional array), with each element of the array being of the string or character base type.\n To create a variable-length string datatype, see \ref_vlen_strings.

Returns:

\hid_t{native datatype} \details H5Tget_native_type() returns the equivalent native datatype identifier for the datatype specified by \p type_id. H5Tget_native_type() is designed primarily to facilitate the use of the H5Dread() function, for which users otherwise must undertake a multi-step process to determine the native datatype of a dataset prior to reading it into memory. This function can be used for the following purposes: \li To determine the native datatype of an atomic datatype \li To determine the base datatype of an array, enumerated, or variable-length datatype \li To determine the native atomic datatypes of the individual components of a compound datatype For example, if \p type_id is a compound datatype, the returned datatype identifier will be for a similar compound datatype with each element converted to the corresponding native datatype; nested compound datatypes will be unwound. If \p type_id is an array, the returned datatype identifier will be for the native datatype of a single array element. H5Tget_native_type() selects the first matching native datatype from the following list: \li #H5T_NATIVE_CHAR \li #H5T_NATIVE_SHORT \li #H5T_NATIVE_INT \li #H5T_NATIVE_LONG \li #H5T_NATIVE_LLONG \li #H5T_NATIVE_UCHAR \li #H5T_NATIVE_USHORT \li #H5T_NATIVE_UINT \li #H5T_NATIVE_ULONG \li #H5T_NATIVE_ULLONG \li #H5T_NATIVE_FLOAT \li #H5T_NATIVE_DOUBLE \li #H5T_NATIVE_LDOUBLE \li #H5T_NATIVE_B8 \li #H5T_NATIVE_B16 \li #H5T_NATIVE_B32 \li #H5T_NATIVE_B64 The direction parameter indicates the order in which the library searches for a native datatype match. Valid values for direction are as follows: \snippet this H5T_direction_t_snip H5Tget_native_type() is designed primarily for use with integer, floating point, and bitfield datatypes. String, time, opaque, and reference datatypes are returned as a copy of dtype_id. See above for compound, array, enumerated, and variable-length datatypes. The identifier returned by H5Tget_native_type() should eventually be closed by calling H5Tclose() to release resources. \note Please note that a datatype is actually an object identifier or handle returned from opening the datatype. It is not persistent, and its value can be different from one HDF5 session to the next. \note H5Tequal() can be used to compare datatypes. \note HDF5 High Level APIs that may also be of interest are: H5LTdtype_to_text() creates a text description of a datatype. H5LTtext_to_dtype() creates an HDF5 datatype given a text description.

Parameters:

Returns:

\herr_t \details H5Tset_size() sets the total size, \p size, in bytes, for a datatype. \p size must have a positive value unless it is passed in as #H5T_VARIABLE and the datatype is a string datatype. \li Numeric datatypes: If the datatype is atomic and the size is decreased so that significant bits of the datatype extend beyond the edge of the new size, then the offset property of the datatype is decreased toward zero. If the offset becomes zero and the significant bits of the datatype still hang over the edge of the new size, then the number of significant bits is decreased. \li String or character datatypes: The size set for a string datatype should include space for the null-terminator character, otherwise it will not be stored on (or retrieved from) the disk. Adjusting the size of a string automatically sets the precision to \p 8*size. \li Variable-length string datatypes: If \p dtype_id is a variable-length string, size must normally be set to #H5T_VARIABLE. See \ref_vlen_strings. \li Compound datatypes: This function may be used to increase or decrease the size of a compound datatype, but the function will fail if the new size is too small to accommodate all member fields. \li Ineligible datatypes: This function cannot be used with enumerated datatypes (#H5T_ENUM), array datatypes (#H5T_ARRAY), variable-length array datatypes (#H5T_VLEN), or reference datatypes (#H5T_REFERENCE).

Returns:

\herr_t \details H5Tset_offset() sets the bit offset of the first significant bit. The significant bits of an atomic datum can be offset from the beginning of the memory for that datum by an amount of padding. The offset property specifies the number of bits of padding that appear “to the right of” the value. That is, if we have a 32-bit datum with 16-bits of precision having the value 0x1122, then it will be laid out in memory as (from small byte address toward larger byte addresses):

 {.unparsed}
          0:  [ pad]  [0x11]  [0x22]  [ pad]
          1:  [ pad]  [0x22]  [0x11]  [ pad]

          3:  [0x22]  [ pad]  [ pad]  [0x11]

Returns:

\herr_t \details H5Tset_strpad() defines the type of padding used for a string datatype. The method used to store character strings differs with the programming language. C usually null terminates strings while Fortran left-justifies and space-pads strings. Valid values of \p strpad are as follows: \str_pad_type When converting from a longer string to a shorter string, the behavior is as follows. If the shorter string is #H5T_STR_NULLPAD or #H5T_STR_SPACEPAD, then the string is simply truncated. If the short string is #H5T_STR_NULLTERM, it is truncated and a null terminator is appended. When converting from a shorter string to a longer string, the longer string is padded on the end by appending nulls or spaces.

Parameters:

nelmts - [in] Size of array \p buf

buf - [in,out] Array containing pre- and post-conversion values

background - [in] Optional background buffer \dxpl_id{plist_id}

Returns:

\herr_t \details H5Tconvert() converts \p nelmts elements from a source datatype, specified by \p src_id, to a destination datatype, \p dst_id. The source elements are packed in \p buf and on return the destination elements will be packed in \p buf. That is, the conversion is performed in place. The optional background buffer is for use with compound datatypes. It is an array of \p nelmts values for the destination datatype which can then be merged with the converted values to recreate the compound datatype. For instance, background might be an array of structs with the \c a and \c b fields already initialized and the conversion of buf supplies the \c c and \c d field values. The parameter \p plist_id contains the dataset transfer property list identifier which is passed to the conversion functions. As of Release 1.2, this parameter is only used to pass along the variable-length datatype custom allocation information. \note H5Tconvert() will not resize the buffer \p buf; it must be large enough to hold the larger of the input and output data.

Returns:

\herr_t \details H5Lmove() moves a link within an HDF5 file. The original link, \p src_name, is removed from \p src_loc and the new link, \p dst_name, is inserted at dst_loc. This change is accomplished as an atomic operation. \p src_loc and \p src_name identify the original link. \p src_loc is the original location identifier; \p src_name is the path to the link and is interpreted relative to \p src_loc. \p dst_loc and \p dst_name identify the new link. \p dst_loc is either a file or group identifier; \p dst_name is the path to the link and is interpreted relative to \p dst_loc. \p lcpl_id and \p lapl_id are the link creation and link access property lists, respectively, associated with the new link, \p dst_name. Through these property lists, several properties are available to govern the behavior of H5Lmove(). The property controlling creation of missing intermediate groups is set in the link creation property list with H5Pset_create_intermediate_group(); H5Lmove() ignores any other properties in the link creation property list. Properties controlling character encoding, link traversals, and external link prefixes are set in the link access property list with H5Pset_char_encoding(), H5Pset_nlinks(), and H5Pset_elink_prefix(), respectively. \note Note that H5Lmove() does not modify the value of the link; the new link points to the same object as the original link pointed to. Furthermore, if the object pointed to by the original link was already open with a valid object identifier, that identifier will remain valid after the call to H5Lmove(). \attention Exercise care in moving links as it is possible to render data in a file inaccessible with H5Lmove(). If the link being moved is on the only path leading to an HDF5 object, that object may become permanently inaccessible in the file.

\ingroup H5L \brief Creates a hard link to an object \fgdta_loc_id{cur_loc}

Parameters:

dst_name - [in] The name of the new link \lcpl_id \lapl_id

Returns:

\herr_t \details H5Lcreate_hard() creates a new hard link to a pre-existing object in an HDF5 file. \p cur_loc and \p cur_name specify the location and name, respectively, of the target object, i.e., the object that the new hard link points to. \p dst_loc and \p dst_name specify the location and name, respectively, of the new hard link. \p cur_name and \p dst_name are interpreted relative to \p cur_loc and \p dst_loc, respectively. If \p cur_loc and \p dst_loc are the same location, the HDF5 macro #H5L_SAME_LOC can be used for either parameter (but not both). \p lcpl_id and \p lapl_id are the link creation and access property lists associated with the new link. \note Hard and soft links are for use only if the target object is in the current file. If the desired target object is in a different file from the new link, an external link may be created with H5Lcreate_external(). \note The HDF5 library keeps a count of all hard links pointing to an object; if the hard link count reaches zero (0), the object will be deleted from the file. Creating new hard links to an object will prevent it from being deleted if other links are removed. The library maintains no similar count for soft links and they can dangle. \note The new link may be one of many that point to that object.

link_name - [in] The name of the new link \lcpl_id \lapl_id

Returns:

\herr_t \details H5Lcreate_soft() creates a new soft link to an object in an HDF5 file. \p link_target specifies the HDF5 path name the soft link contains. \p link_target can be an arbitrary HDF5 path name and is interpreted only at lookup time. This path may be absolute in the file or relative to \p link_loc_id. \p link_loc_id and \p link_name specify the location and name, respectively, of the new soft link. \p link_name is interpreted relative to \p link_loc_id and must contain only the name of the soft link; \p link_name may not contain any additional path elements. If \p link_loc_id is a group identifier, the object pointed to by \p link_name will be accessed as a member of that group. If \p link_loc_id is a file identifier, the object will be accessed as a member of the file's root group. \p lcpl_id and \p lapl_id are the link creation and access property lists associated with the new link. For instance, if target_path is \c ./foo, \p link_loc_id specifies \c ./x/y/bar, and the name of the new link is \c new_link, then a subsequent request for \c ./x/y/bar/new_link will return the same object as would be found at \c ./foo. \note H5Lcreate_soft() is for use only if the target object is in the current file. If the desired target object is in a different file from the new link, use H5Lcreate_external() to create an external link. \note Soft links and external links are also known as symbolic links as they use a name to point to an object; hard links employ an object’s address in the file. \note Unlike hard links, a soft link in an HDF5 file is allowed to dangle, meaning that the target object need not exist at the time that the link is created. \note The HDF5 library does not keep a count of soft links as it does of hard links. \note The new link may be one of many that point to that object.

\ingroup H5L \brief Removes a link from a group \fgdta_loc_id

Parameters:

name - [in] Name of the link to delete \lapl_id

Returns:

\herr_t \details H5Ldelete() removes the link specified by \p name from the location \p loc_id. If the link being removed is a hard link, H5Ldelete() also decrements the link count for the object to which name points. Unless there is a duplicate hard link in that group, this action removes the object to which name points from the group that previously contained it. Object headers keep track of how many hard links refer to an object; when the hard link count, also referred to as the reference count, reaches zero, the object can be removed from the file. The file space associated will then be released, i.e., identified in memory as freespace. Objects which are open are not removed until all identifiers to the object are closed. \attention Exercise caution in the use of H5Ldelete(); if the link being removed is on the only path leading to an HDF5 object, that object may become permanently inaccessible in the file.

For external and user-defined links, it is the link buffer. \p size is the size of \p buf and should be the size of the link value being returned. This size value can be determined through a call to H5Lget_info(); it is returned in the \c val_size field of the \ref H5L_info_t \c struct. If \p size is smaller than the size of the returned value, then the string stored in \p buf will be truncated to \p size bytes. For soft links, this means that the value will not be null terminated. In the case of external links, the target file and object names are extracted from \p buf by calling H5Lunpack_elink_val(). The link class of link \p name can be determined with a call to H5Lget_info(). \p lapl_id specifies the link access property list associated with the link \p name. In the general case, when default link access properties are acceptable, this can be passed in as #H5P_DEFAULT. An example of a situation that requires a non-default link access property list is when the link is an external link; an external link may require that a link prefix be set in a link access property list (see H5Pset_elink_prefix()). This function should be used only after H5Lget_info() has been called to verify that \p name is a symbolic link. This can be determined from the \c link_type field of the \ref H5L_info_t \c struct. \note This function will fail if called on a hard link.

\herr_t \details H5Lget_val_by_idx() retrieves the value of the \Emph{n}-th link in a group, according to the specified order, \p order, within an index, \p index. For soft links, the value is an HDF5 path name. For external links, this is a compound value containing file and path name information; to use this external link information, it must first be decoded with H5Lunpack_elink_val() For user-defined links, this value will be described in the definition of the user-defined link type. \p loc_id specifies the location identifier of the group specified by \p group_name. \p group_name specifies the group in which the link exists. If \p loc_id already specifies the group in which the link exists, \p group_name must be a dot (\c .). The size in bytes of link_val is specified in \p size. The size value can be determined through a call to H5Lget_info_by_idx(); it is returned in the \c val_size field of the \ref H5L_info_t \c struct. If size is smaller than the size of the returned value, then the string stored in link_val will be truncated to size bytes. For soft links, this means that the value will not be null terminated. If the type of the link is unknown or uncertain, H5Lget_val_by_idx() should be called only after the type has been determined via a call to H5Lget_info_by_idx(). \note This function will fail if called on a hard link.

\ingroup H5L \brief Determines whether a link with the specified name exists in a group \fgdta_loc_id

Parameters:

name - [in] Link name \lapl_id

Returns:

\herr_t \details H5Lexists() allows an application to determine whether the link \p name exists in the location specified by \p loc_id. The link may be of any type; only the presence of a link with that name is checked. Note that H5Lexists() verifies only that the target link exists. If name includes either a relative path or an absolute path to the target link, intermediate steps along the path must be verified before the existence of the target link can be safely checked. If the path is not verified, and an intermediate element of the path does not exist, H5Lexists() will fail. The example in the next paragraph illustrates one step-by-step method for verifying the existence of a link with a relative or absolute path. \Bold{Example:} Use the following steps to verify the existence of the link \c datasetD in the \c group group1/group2/softlink_to_group3/, where \c group1 is a member of the group specified by \c loc_id: 1. First, use H5Lexists() to verify that the \c group1 exists. 2. If \c group1 exists, use H5Lexists() again, this time with name set to \c group1/group2, to verify that \c group2 exists. 3. If \c group2 exists, use H5Lexists() with name set to \c group1/group2/softlink_to_group3 to verify that \c softlink_to_group3 exists. 4. If \c softlink_to_group3 exists, you can now safely use H5Lexists() with \c name set to \c group1/group2/softlink_to_group3/datasetD to verify that the target link, \c datasetD, exists. If the link to be verified is specified with an absolute path, the same approach should be used, but starting with the first link in the file’s root group. For instance, if \c datasetD were in \c /group1/group2/softlink_to_group3, the first call to H5Lexists() would have name set to \c /group1. Note that this is an outline and does not include all the necessary details. Depending on circumstances, for example, you may need to verify that an intermediate link points to a group and that a soft link points to an existing target. \note The behavior of H5Lexists() was changed in the 1.10 release in the case where the root group, \c "/", is the name of the link. This change is described below:

1. Let \c file denote a valid HDF5 file identifier, and let \c lapl denote a valid link access property list identifier. A call to H5Lexists() with arguments \c file, \c "/", and \c lapl returns a positive value; in other words, \Code{H5Lexists(file, "/", lapl)} returns a positive value. In the HDF5 1.8 release, this function returns 0.
2. Let \c root denote a valid HDF5 group identifier that refers to the root group of an HDF5 file, and let \c lapl denote a valid link access property list identifier. A call to H5Lexists() with arguments c root, \c "/", and \c lapl returns a positive value; in other words, \Code{H5Lexists(root, "/", lapl)} returns a positive value. In the HDF5 1.8 release, this function returns 0.

Note that the function accepts link names and path names. This is potentially misleading to callers, and we plan to separate the functionality for link names and path names in a future release. \attention H5Lexists() checks the existence of only the final element in a relative or absolute path; it does not check any other path elements. The function will therefore fail when both of the following conditions exist: - \c name is not local to the group specified by \c loc_id or, if \c loc_id is something other than a group identifier, \c name is not local to the root group. - Any element of the relative path or absolute path in name, except the target link, does not exist.

Parameters:

name - [in] Link name

linfo - [out] Buffer in which link information is returned \lapl_id

Returns:

\herr_t \details H5Lget_info2() returns information about the specified link through the \p linfo argument. The location identifier, \p loc_id, specifies the location of the link. A link name, \p name, interpreted relative to \p loc_id, specifies the link being queried. \p lapl_id is the link access property list associated with the link name. In the general case, when default link access properties are acceptable, this can be passed in as #H5P_DEFAULT. An example of a situation that requires a non-default link access property list is when the link is an external link; an external link may require that a link prefix be set in a link access property list (see H5Pset_elink_prefix()). H5Lget_info2() returns information about name in the data structure H5L_info2_t, which is described below and defined in H5Lpublic.h. This structure is returned in the buffer \p linfo. \snippet this H5L_info2_t_snip In the above struct, \c type specifies the link class. Valid values include the following: \link_types There will be additional valid values if user-defined links have been registered. \p corder specifies the link’s creation order position, while \p corder_valid indicates whether the value in corder is valid. If \p corder_valid is \c TRUE, the value in \p corder is known to be valid; if \p corder_valid is \c FALSE, the value in \p corder is presumed to be invalid; \p corder starts at zero (0) and is incremented by one (1) as new links are created. But higher-numbered entries are not adjusted when a lower-numbered link is deleted; the deleted link's creation order position is simply left vacant. In such situations, the value of \p corder for the last link created will be larger than the number of links remaining in the group. \p cset specifies the character set in which the link name is encoded. Valid values include the following: \csets This value is set with #H5Pset_char_encoding. \c token is the location that a hard link points to, and \c val_size is the size of a soft link or user-defined link value. H5O_token_t is used in the VOL layer. It is defined in H5public.h as: \snippet H5public.h H5O_token_t_snip If the link is a symbolic link, \c val_size will be the length of the link value, e.g., the length of the HDF5 path name with a null terminator.

\ingroup H5L \brief Retrieves metadata for a link in a group, according to the order within a field or index \loc_id

Parameters:

group_name - [in] Group name \idx_type \order

n - [in] Link position for which to retrieve information

linfo - [out] Buffer in which link information is returned \lapl_id

Returns:

\herr_t \details H5get_info_by_idx2() returns the metadata for a link in a group according to a specified field or index and a specified order. The link for which information is to be returned is specified by \p idx_type, \p order, and \p n as follows: - \p idx_type specifies the field by which the links in \p group_name are ordered. The links may be indexed on this field, in which case operations seeking specific links are likely to complete more quickly. - \p order specifies the order in which the links are to be referenced for the purposes of this function. - \p n specifies the position of the subject link. Note that this count is zero-based; 0 (zero) indicates that the function will return the value of the first link; if \p n is 5, the function will return the value of the sixth link; etc. For example, assume that \p idx_type, \p order, and \p n are #H5_INDEX_NAME, #H5_ITER_DEC, and 5, respectively. #H5_INDEX_NAME indicates that the links are accessed in lexicographic order by their names. #H5_ITER_DEC specifies that the list be traversed in reverse order, or in decremented order. And 5 specifies that this call to the function will return the metadata for the 6th link (\c n + 1) from the end. See H5Literate2() for a list of valid values and further discussion regarding \p idx_type and \p order. If \p loc_id specifies the group in which the link resides, \p group_name can be a dot (\c .).

\ingroup H5L \brief Retrieves name of the \Emph{n}-th link in a group, according to the order within a specified field or index \loc_id

Parameters:

group_name - [in] Group name \idx_type \order

n - [in] Link position for which to retrieve information

name - [out] Buffer in which link name is returned

size - [in] Size in bytes of \p name \lapl_id

Returns:

Returns the size of the link name if successful; otherwise returns a negative value. \details H5get_name_by_idx() retrieves the name of the \Emph{n}-th link in a group, according to the specified order, \p order, within a specified field or index, \p idx_type. \p idx_type specifies the index that is used. Valid values include the following: \indexes \p order specifies the order in which objects are inspected along the index specified in \p idx_type. Valid values include the following: \orders If \p loc_id specifies the group in which the link resides, \p group_name can be a dot (\c .). The size in bytes of name is specified in \p size. If \p size is unknown, it can be determined via an initial H5Lget_name_by_idx() call with name set to NULL; the function's return value will be the size of the name. \note Please note that in order for the specified index to correspond to the creation order index, \p order must be set to #H5_ITER_INC or #H5_ITER_DEC when calling H5Lget_name_by_idx(). \note The index \p n passed to H5Lget_name_by_idx() is the index of the link within the link table, sorted according to \p order and \p idx_type. If order is #H5_ITER_NATIVE, then the link table is not sorted, and it does not matter what \p idx_type is. Specifying #H5_ITER_NATIVE does not guarantee any particular order, only that it remains consistent.

Parameters:

group_name - [in] Group name \idx_type \order \op \op_data \lapl_id

Returns:

\herr_t \details H5Lvisit_by_name2() is a recursive iteration function to visit all links in and below a group in an HDF5 file, thus providing a mechanism for an application to perform a common set of operations across all of those links or a dynamically selected subset. For non-recursive iteration across the members of a group, see H5Literate2(). The group serving as the root of the iteration is specified by the \p loc_id / \p group_name parameter pair. \p loc_id specifies a file or group; group_name specifies either a group in the file (with an absolute name based in the file’s root group) or a group relative to \p loc_id. If \p loc_id fully specifies the group that is to serve as the root of the iteration, group_name should be '.' (a dot). (Note that when \p loc_id fully specifies the group that is to serve as the root of the iteration, the user may wish to consider using H5Lvisit2() instead of H5Lvisit_by_name2().) Two parameters are used to establish the iteration: \p idx_type and \p order. \p idx_type specifies the index to be used. If the links have not been indexed by the index type, they will first be sorted by that index then the iteration will begin; if the links have been so indexed, the sorting step will be unnecessary, so the iteration may begin more quickly. Valid values include the following: \indexes Note that the index type passed in \p idx_type is a best effort setting. If the application passes in a value indicating iteration in creation order and a group is encountered that was not tracked in creation order, that group will be iterated over in lexicographic order by name, or name order. (Name order is the native order used by the HDF5 library and is always available.) \p order specifies the order in which objects are to be inspected along the index specified in \p idx_type. Valid values include the following: \orders The \p op callback function, the related \ref H5L_info2_t \c struct, and the effect that the callback function's return value has on the application are described in H5Lvisit2(). The H5Lvisit_by_name2() \p op_data parameter is a user-defined pointer to the data required to process links in the course of the iteration. This pointer is passed back to each step of the iteration in the callback function's \p op_data parameter. \p lapl_id is a link access property list. In the general case, when default link access properties are acceptable, this can be passed in as #H5P_DEFAULT. An example of a situation that requires a non-default link access property list is when the link is an external link; an external link may require that a link prefix be set in a link access property list (see H5Pset_elink_prefix()). H5Lvisit_by_name2() and H5Ovisit_by_name2() are companion functions: one for examining and operating on links; the other for examining and operating on the objects that those links point to. Both functions ensure that by the time the function completes successfully, every link or object below the specified point in the file has been presented to the application for whatever processing the application requires.

udata - [in] User-supplied link information

udata_size - [in] Size of udata buffer \lcpl_id \lapl_id

Returns:

\herr_t \details H5Lcreate_ud() creates a link of user-defined type \p link_type named \p link_name at the location specified in \p link_loc_id with user-specified data \p udata. \p link_name is interpreted relative to \p link_loc_id. Valid values for the link class of the new link, \p link_type, include #H5L_TYPE_EXTERNAL and any user-defined link classes that have been registered with the library. See H5Lregister() for further information. The format of the information pointed to by \p udata is defined by the user. \p udata_size specifies the size of the \p udata buffer. \p udata may be NULL if \p udata_size is zero (0). The property lists specified by \p lcpl_id and \p lapl_id specify properties used to create and access the link. \note The external link type, #H5L_TYPE_EXTERNAL, included in the HDF5 library distribution, is implemented as a user-defined link type. This was done, in part, to provide a model for the implementation of other user-defined links.

flags - [out] External link flags, packed as a bitmap (\Emph{Reserved as a bitmap for flags; no flags are currently defined, so the only valid value * is 0.})

Returns:

\herr_t \details H5Lunpack_elink_val() decodes the external link information returned by H5Lget_val() in the \p ext_linkval buffer. \p ext_linkval should be the buffer set by H5Lget_val() and will consist of two NULL-terminated strings, the filename and object path, one after the other. Given this buffer, H5Lunpack_elink_val() creates pointers to the filename and object path within the buffer and returns them in \p filename and \p obj_path, unless they are passed in as NULL. H5Lunpack_elink_val() requires that \p ext_linkval contain a concatenated pair of null-terminated strings, so use of this function on a string that is not an external link \p udata buffer may result in a segmentation fault. This failure can be avoided by adhering to the following procedure:

1. Call H5Lget_info() to get the link type and the size of the link value.
3. Verify that the link is an external link, i.e., that its link type is #H5L_TYPE_EXTERNAL.
4. Call H5Lget_val() to get the link value.
5. Call H5Lunpack_elink_val() to unpack that value.

\ingroup H5L \brief Creates an external link, a soft link to an object in a different file.

Parameters:

file_name - [in] Name of the target file containing the target object.

obj_name - [in] Path within the target file to the target object \fgdt_loc_id{link_loc_id}

link_name - [in] Name of the new link, relative to \p link_loc_id \lcpl_id \lapl_id

Returns:

\herr_t \details H5Lcreate_external() creates a new external link. An external link is a soft link to an object in a different HDF5 file from the location of the link, i.e., to an external object. \p file_name identifies the target file containing the target object; \p obj_name specifies the path of the target object within that file. \p obj_name must be an absolute pathname in \p file_name, i.e., it must start at the target file’s root group, but it is not interpreted until an application attempts to traverse it. \p link_loc_id and \p link_name specify the location and name, respectively, of the new link. \p link_name is interpreted relative to \p link_loc_id. \p lcpl_id is the link creation property list used in creating the new link. \p lapl_id is the link access property list used in traversing the new link. Note that an external file opened by the traversal of an external link is always opened with the weak file close degree property setting, #H5F_CLOSE_WEAK (see H5Pset_fclose_degree()); any file close degree property setting in \p lapl_id is ignored. An external link behaves similarly to a soft link, and like a soft link in an HDF5 file, it may dangle: the target file and object need not exist at the time that the external link is created. When the external link \p link_name is accessed, the library will search for the target file \p file_name as described below: - If \p file_name is a relative pathname, the following steps are performed: - The library will get the prefix(es) set in the environment variable \c HDF5_EXT_PREFIX and will try to prepend each prefix to \p file_name to form a new \p file_name. - If the new \p file_name does not exist or if \c HDF5_EXT_PREFIX is not set, the library will get the prefix set via H5Pset_elink_prefix() and prepend it to \p file_name to form a new \p file_name. - If the new \p file_name does not exist or no prefix is being set by H5Pset_elink_prefix(), then the path of the file associated with \p link_loc_id is obtained. This path can be the absolute path or the current working directory plus the relative path of that file when it is created/opened. The library will prepend this path to \p file_name to form a new \p file_name. - If the new \p file_name does not exist, then the library will look for \p file_name and will return failure/success accordingly. - If \p file_name is an absolute pathname, the library will first try to find \p file_name. If \p file_name does not exist, \p file_name is stripped of directory paths to form a new \p file_name. The search for the new \p file_name then follows the same steps as described above for a relative pathname. See examples below illustrating how target_file_name is stripped to form a new \p file_name. Note that \p file_name is considered to be an absolute pathname when the following condition is true: - For Unix, the first character of \p file_name is a slash (\c /). For example, consider a \p file_name of \c /tmp/A.h5. If that target file does not exist, the new \p file_name after stripping will be \c A.h5. - For Windows, there are 6 cases: -# \p file_name is an absolute drive with an absolute pathname. For example, consider a \p file_name of \c /tmp/A.h5. If that target file does not exist, the new \p file_name after stripping will be \c A.h5. -# \p file_name is an absolute pathname without specifying drive name. For example, consider a \p file_name of \c /tmp/A.h5. If that target file does not exist, the new \p file_name after stripping will be \c A.h5. -# \p file_name is an absolute drive with a relative pathname. For example, consider a \p file_name of \c /tmp/A.h5. If that target file does not exist, the new \p file_name after stripping will be \c tmp\A.h5. -# \p file_name is in UNC (Uniform Naming Convention) format with a server name, share name, and pathname. For example, consider a \p file_name of \c /tmp/A.h5. If that target file does not exist, the new \p file_name after stripping will be \c A.h5. -# \p file_name is in Long UNC (Uniform Naming Convention) format with a server name, share name, and pathname. For example, consider a \p file_name of \c /tmp/A.h5. If that target file does not exist, the new \p file_name after stripping will be \c A.h5. -# \p file_name is in Long UNC (Uniform Naming Convention) format with an absolute drive and an absolute pathname. For example, consider a \p file_name of \c /tmp/A.h5. If that target file does not exist, the new \p file_name after stripping will be \c A.h5. The library opens the target file \p file_name with the file access property list that is set via H5Pset_elink_fapl() when the external link link_name is accessed. If no such property list is set, the library uses the file access property list associated with the file of \p link_loc_id to open the target file. If an application requires additional control over file access flags or the file access property list, see H5Pset_elink_cb(); this function enables the use of an external link callback function as described in H5L_elink_traverse_t(). \attention A file close degree property setting (H5Pset_fclose_degree()) in the external link file access property list or in the external link callback function will be ignored. A file opened by means of traversing an external link is always opened with the weak file close degree property setting, #H5F_CLOSE_WEAK .

Parameters:

name - [in] Path to the object; relative to \p loc_id \lapl_id

Returns:

\hid_tv{object} \details H5Oopen() opens a group, dataset, or committed (named) datatype specified by a location, \p loc_id, and a path name, \p name, in an HDF5 file. This function opens the object in the same manner as H5Gopen(), H5Topen(), and H5Dopen(). However, H5Oopen() does not require the type of object to be known beforehand. This can be useful with user-defined links, for instance, when only a path may be known. H5Oopen() cannot be used to open a dataspace, attribute, property list, or file. Once an object of an unknown type has been opened with H5Oopen(), the type of that object can be determined by means of an H5Iget_type() call. \p loc_id may be a file, group, dataset, named datatype, or attribute. If an attribute is specified for \p loc_id then the object where the attribute is attached will be accessed. \p name must be the path to that object relative to \p loc_id. \p lapl_id is the link access property list associated with the link pointing to the object. If default link access properties are appropriate, this can be passed in as #H5P_DEFAULT. When it is no longer needed, the opened object should be closed with H5Oclose(), H5Gclose(), H5Tclose(), or H5Dclose().

\hid_tv{object} \details H5Oopen_by_idx() opens the nth object in the group specified by \p loc_id and \p group_name. \p loc_id specifies a location identifier. \p group_name specifies the group relative to \p loc_id in which the object can be found. If \p loc_id fully specifies the group in which the object resides, \p group_name can be a dot (.). The specific object to be opened within the group is specified by the three parameters: \p idx_type, \p order and \p n. \p idx_type specifies the type of index by which objects are ordered. Valid index types include the following: \indexes \p order specifies the order in which the objects are to be referenced for the purposes of this function. Valid orders include the following: \orders Note that for #H5_ITER_NATIVE, rather than implying a particular order, it instructs the HDF5 library to iterate through the objects in the fastest available order, i.e., in a natural order. \p n specifies the position of the object within the index. Note that this count is zero-based; 0 (zero) indicates that the function will return the value of the first object; if \p n is 5, the function will return the value of the sixth object; etc. \p lapl_id specifies the link access property list to be used in accessing the object. An object opened with this function should be closed when it is no longer needed so that resource leaks will not develop. H5Oclose() can be used to close groups, datasets, or committed datatypes.

These flags are defined in the H5Opublic.h file: \obj_info_fields \par Example An example snippet from examples/h5_attribute.c: \par \snippet h5_attribute.c H5Oget_info3_snip \note If you are iterating through a lot of different objects to retrieve information via the H5Oget_info() family of routines, you may see memory building up. This can be due to memory allocation for metadata, such as object headers and messages, when the iterated objects are put into the metadata cache. \note If the memory buildup is not desirable, you can configure a smaller cache via H5Fset_mdc_config() or set the file access property list via H5Pset_mdc_config(). A smaller sized cache will force metadata entries to be evicted from the cache, thus freeing the memory associated with the entries.

------------------------------------------------------------------------- \ingroup H5O \brief Creates a hard link to an object in an HDF5 file

Parameters:

obj_id - [in] Object to be linked

new_loc_id - [in] Location identifier at which object is to be linked; may be a file, group, dataset, named datatype or attribute identifier.

new_name - [in] Name of link to be created, relative to \p new_loc_id. \lcpl_id \lapl_id

Returns:

\herr_t \details H5Olink() creates a new hard link to an object in an HDF5 file. \p new_loc_id and \p \p new_link_name specify the location and name of the new link, while \p object_id identifies the object that the link points to. H5Olink() is designed for two purposes: - To create the first hard link to an object that has just been created with H5Dcreate_anon(), H5Gcreate_anon(), or H5Tcommit_anon(). - To add additional structure to an existing file so that, for example, an object can be shared among multiple groups. \p lcpl and \p lapl are the link creation and access property lists associated with the new link. \par Example: To create a new link to an object while simultaneously creating missing intermediate groups: Suppose that an application must create the group C with the path /A/B01/C but may not know at run time whether the groups A and B01 exist. The following code ensures that those groups are created if they are missing: \par

      // Creates a link creation property list (LCPL).
      hid_t lcpl_id = H5Pcreate(H5P_LINK_CREATE);

      // Sets "create missing intermediate groups" property in that LCPL.
      int status = H5Pset_create_intermediate_group(lcpl_id, TRUE);

      // Creates a group without linking it into the file structure.
      hid_t gid  = H5Gcreate_anon(file_id, H5P_DEFAULT, H5P_DEFAULT);

      // Links group into file structure.
      status = H5Olink(gid, file_id, "/A/B01/C", lcpl_id, H5P_DEFAULT);

 

\par Note that unless the object is intended to be temporary, the H5O_LINK call is mandatory if an object created with one of the H5*_CREATE_ANON functions (or with H5T_COMMIT_ANON) is to be retained in the file; without an H5O_LINK call, the object will not be linked into the HDF5 file structure and will be deleted when the file is closed.

Parameters:

src_loc_id - [in] Object identifier indicating the location of the source object to be copied

src_name - [in] Name of the source object to be copied

dst_loc_id - [in] Location identifier specifying the destination

dst_name - [in] Name to be assigned to the new copy

ocpypl_id - [in] Object copy property list \lcpl_id

Returns:

\herr_t \details H5Ocopy() copies the group, dataset or committed datatype specified by \p src_name from the file or group specified by \p src_loc_id to the destination location \p dst_loc_id. The destination location, as specified in dst_loc_id, may be a group in the current file or a location in a different file. If dst_loc_id is a file identifier, the copy will be placed in that file’s root group. The copy will be created with the path specified in \p dst_name, which must not pre-exist in the destination location. If \p dst_name already exists at the location \p dst_loc_id, H5Ocopy() will fail. If \p dst_name is an absolute path, the copy will be created relative to the file’s root group. The copy of the object is created with the property lists specified by \p ocpypl_id and \p lcpl_id. #H5P_DEFAULT can be passed in for these property lists. The default behavior: - of the link creation property list is to NOT create intermediate groups. - of the flags specified by the object creation property list is described in H5Pset_copy_object(). These property lists or flags can be modified to govern the behavior of H5Ocopy() as follows: - A flag controlling the creation of intermediate groups that may not yet exist is set in the link creation property list \p lcpl_id with H5Pset_create_intermediate_group(). - Copying of committed datatypes can be tuned through the use of H5Pset_copy_object(), H5Padd_merge_committed_dtype_path(), H5Pset_mcdt_search_cb(), and related functions. - Flags controlling other aspects of object copying are set in the object copy property list \p ocpypl_id with H5Pset_copy_object(). H5Ocopy() will always try to make a copy of the object specified in \p src_name. - If the object specified by \p src_name is a group containing a soft or external link, the default is that the new copy will contain a soft or external link with the same value as the original. See H5Pset_copy_object() for optional settings. - If the path specified in \p src_name is or contains a soft link or an external link, H5Ocopy() will copy the target object. Use H5Lcopy() if the intent is to create a new soft or external link with the same value as the original link. H5Ocopy() can be used to copy an object in an HDF5 file. If an object has been changed since it was opened, it should be written back to the file before using H5Ocopy(). The object can be written back either by closing the object (H5Gclose(), H5Oclose(), H5Dclose(), or H5Tclose()) or by flushing the HDF5 file (H5Fflush()). \par See Also: - Functions to modify the behavior of H5Ocopy(): - H5Padd_merge_committed_dtype_path() - H5Pset_copy_object() - H5Pset_create_intermediate_group() - H5Pset_mcdt_search_cb() - Copying Committed Datatypes with #H5Ocopy - A comprehensive discussion of copying committed datatypes (PDF) in Advanced Topics in HDF5

Returns:

Upon success, returns the number of characters in the comment, not including the \c NULL terminator, or zero (\c 0) if the object has no comment. The value returned may be larger than \p bufsize. Otherwise returns a negative value. \details H5Oget_comment() retrieves the comment for the specified object in the buffer \p comment. The target object is specified by an identifier, \p object_id. The size in bytes of the buffer \p comment, including the \c NULL terminator, is specified in \p bufsize. If \p bufsize is unknown, a preliminary H5Oget_comment() call with the pointer \p comment set to \c NULL will return the size of the comment without the \c NULL terminator. If \p bufsize is set to a smaller value than described above, only \p bufsize bytes of the comment, without a \c NULL terminator, are returned in \p comment. If an object does not have a comment, an empty string is returned in \p comment.

------------------------------------------------------------------------- \ingroup H5O \brief Retrieves comment for specified object \fgdta_loc_obj_id{loc_id}

Parameters:

name - [in] Name of the object whose comment is to be retrieved

comment - [out] The comment

bufsize - [in] Anticipated required size of the \p comment buffer \lapl_id

Returns:

Upon success, returns the number of characters in the comment, not including the \c NULL terminator, or zero (\c 0) if the object has no comment. The value returned may be larger than \c bufsize. Otherwise returns a negative value. \details H5Oget_comment_by_name() retrieves the comment for an object in the buffer \p comment. The target object is specified by \p loc_id and \p name. \p loc_id can specify any object in the file. \p name can be one of the following: - The name of the object relative to \p loc_id - An absolute name of the object, starting from \c /, the file’s root group - A dot (\c .), if \p loc_id fully specifies the object The size in bytes of the comment, including the \c NULL terminator, is specified in \p bufsize. If \p bufsize is unknown, a preliminary H5Oget_comment_by_name() call with the pointer \p comment set to \c NULL will return the size of the comment without the \c NULL terminator. If \p bufsize is set to a smaller value than described above, only \p bufsize bytes of the comment, without a \c NULL terminator, are returned in \p comment. If an object does not have a comment, an empty string is returned in \p comment. \p lapl_id contains a link access property list identifier. A link access property list can come into play when traversing links to access an object.

Returns:

\herr_t \details H5Oflush() causes all buffers associated with an object to be immediately flushed to disk without removing the data from the cache. The object associated with \p object_id can be any named object in an HDF5 file, including a dataset, a group, or a committed datatype. \warning H5Oflush doesn't work correctly with parallel. It causes an assertion failure in metadata cache during H5Fclose(). \note HDF5 does not possess full control over buffering. H5Oflush() flushes the internal HDF5 buffers and then asks the operating system (the OS) to flush the system buffers for the open files. After that, the OS is responsible for ensuring that the data is actually flushed to disk.

Parameters:

Returns:

\herr_t \details H5Odisable_mdc_flushes(), H5Oenable_mdc_flushes() and associated flush functions can be used to control the flushing of entries from a file’s metadata cache. This function prevents an object’s or cache’s dirty metadata entries from being flushed from the cache by the usual cache eviction/flush policy. Instead, users must manually flush the cache or entries for individual objects via the appropriate H5Fflush(), H5Dflush(), H5Gflush(), H5Tflush(), and H5Oflush() calls. Metadata cache entries can be controlled at both the individual HDF5 object level (datasets, groups, committed datatypes) and the entire metadata cache level. \note HDF5 objects include datasets, groups, and committed datatypes. Only #hid_t identifiers that represent these objects can be passed to the function. Passing in a #hid_t identifier that represents any other HDF5 entity is considered an error. It is an error to pass an HDF5 file identifier (obtained from H5Fopen() or H5Fcreate()) to this function. Misuse of this function can cause the cache to exhaust available memory. Objects can be returned to the default automatic flush behavior with H5Oenable_mdc_flushes(). Flush prevention only pertains to new or dirty metadata entries. Clean entries can be evicted from the cache. Calling this function on an object that has already had flushes disabled will return an error.

\ingroup H5Z \brief Retrieves information about a filter

Parameters:

filter - [in] Filter identifier

filter_config_flags - [out] A bit field encoding the returned filter information

Returns:

\herr_t \details H5Zget_filter_info() retrieves information about a filter. At present, this means that the function retrieves a filter's configuration flags, indicating whether the filter is configured to decode data, encode data, neither, or both. If \p filter_config_flags is not set to NULL prior to the function call, the returned parameter contains a bit field specifying the available filter configuration. The configuration flag values can then be determined through a series of bitwise AND operations, as described below. Valid filter configuration flags include the following:

#H5Z_FILTER_CONFIG_ENCODE_ENABLED	Encoding is enabled for this filter
#H5Z_FILTER_CONFIG_DECODE_ENABLED	Decoding is enabled for this filter

A bitwise AND of the returned \p filter_config_flags and a valid filter configuration flag will reveal whether the related configuration option is available. For example, if the value of

          H5Z_FILTER_CONFIG_ENCODE_ENABLED & filter_config_flags
          

is true, i.e., greater than 0 (zero), the queried filter is configured to encode data; if the value is \c FALSE, i.e., equal to 0 (zero), the filter is not so configured. If a filter is not encode-enabled, the corresponding \c H5Pset_* function will return an error if the filter is added to a dataset creation property list (which is required if the filter is to be used to encode that dataset). For example, if the #H5Z_FILTER_CONFIG_ENCODE_ENABLED flag is not returned for the SZIP filter, #H5Z_FILTER_SZIP, a call to H5Pset_szip() will fail. If a filter is not decode-enabled, the application will not be able to read an existing file encoded with that filter. This function should be called, and the returned \p filter_config_flags should be analyzed, before calling any other function, such as H5Pset_szip(), that might require a particular filter configuration.

Parameters:

buf_size - [in] The size of the buffer to store the name in

buf - [out] Buffer to store name in

Returns:

Returns the length of the attribute's name, which may be longer than \p buf_size, if successful. Otherwise, returns a negative value. \details H5Aget_name() retrieves the name of an attribute specified by the identifier, \p attr_id. Up to \p buf_size characters are stored in \p buf followed by a \0 string terminator. If the name of the attribute is longer than (\p buf_size -1), the string terminator is stored in the last position of the buffer to properly terminate the string. If the user only wants to retrieve the name length, the values 0 and NULL should be passed for the parameters \p bufsize and \p buf.

\ingroup H5A \brief Calls a user-defined function for each attribute on an object \fgdt_loc_id

Parameters:

idx_type - [in] Type of index

order - [in] Order in which to iterate over index

idx - [in,out] Initial and returned offset within index

op - [in] User-defined function to pass each attribute to

op_data - [in,out] User data to pass through to and to be returned by iterator operator function

Returns:

\herr_t Further note that this function returns the return value of the last operator if it was non-zero, which can be a negative value, zero if all attributes were processed, or a positive value indicating short-circuit success. \details H5Aiterate2() iterates over the attributes attached to a dataset, named datatype, or group, as specified by \p loc_id. For each attribute, user-provided data, \p op_data, with additional information as defined below, is passed to a user-defined function, \p op, which operates on that attribute. The order of the iteration and the attributes iterated over are specified by three parameters: the index type, \p idx_type; the order in which the index is to be traversed, \p order; and the attribute’s position in the index, \p idx. The next attribute to be operated on is specified by \p idx, a position in the index. For example, if \p idx_type, \p order, and \p idx are set to #H5_INDEX_NAME, #H5_ITER_INC, and 5, respectively, the attribute in question is the fifth attribute from the beginning of the alphanumeric index of attribute names. If \p order were set to #H5_ITER_DEC, it would be the fifth attribute from the end of the index. The parameter \p idx is passed in on an H5Aiterate2() call with one value and may be returned with another value. The value passed in identifies the parameter to be operated on first; the value returned identifies the parameter to be operated on in the next step of the iteration. \note This function is also available through the H5Aiterate() macro.

Parameters:

name - [in] Name of the dataset to create \type_id \space_id \lcpl_id \dcpl_id \dapl_id

Returns:

\hid_t{dataset} \details H5Dcreate2() creates a new dataset named \p name at the location specified by \p loc_id, and associates constant and initial persistent properties with that dataset, including the datatype \p dtype_id, the dataspace \p space_id, and other properties as specified by the dataset creation property list \p dcpl_id and the access property list \p dapl_id, respectively. Once created, the dataset is opened for access. \p loc_id may specify a file, group, dataset, named datatype, or attribute. If an attribute, dataset, or named datatype is specified, then the dataset will be created at the location where the attribute, dataset, or named datatype is attached. \p name may be either an absolute path in the file or a relative path from \p loc_id naming the dataset. If \p dtype_id is a committed datatype, and if the file location associated with the committed datatype is different from the file location where the dataset will be created, the datatype is copied and converted to a transient type. The link creation property list, \p lcpl_id, governs the creation of the link(s) by which the new dataset is accessed and the creation of any intermediate groups that may be missing. The datatype and dataspace properties and the dataset creation and access property lists are attached to the dataset, so the caller may derive new datatypes, dataspaces, and creation and access properties from the old ones and reuse them in calls to create additional datasets. Once created, the dataset can be read from or written to. Reading data from a dataset that was not previously written, the HDF5 library will return default or user-defined fill values. \par Example \snippet H5D_examples.c create

Returns:

\hid_t{dataset} \details H5Dcreate_anon() creates a dataset in the file specified by \p loc_id. \p loc_id may specify a file, group, dataset, named datatype, or attribute. If an attribute, dataset, or named datatype is specified, then the dataset will be created at the location where the attribute, dataset, or named datatype is attached. The dataset’s datatype and dataspace are specified by \p type_id and \p space_id, respectively. These are the datatype and dataspace of the dataset as they will exist in the file, which may differ from the datatype and dataspace in application memory. H5Dcreate_anon() returns a new dataset identifier. Using this identifier, the new dataset must be linked into the HDF5 file structure with H5Olink() or it will be deleted when the file is closed.

Parameters:

allocation - [out] Space allocation status

Returns:

\herr_t \details H5Dget_space_status() determines whether space has been allocated for the dataset \p dset_id. \note \Bold{BUG:} Prior to the HDF5 1.14.0, 1.12.2 and 1.10.9 releases, H5Dget_space_status() may return incorrect space allocation status values for datasets with filters applied to them. H5Dget_space_status() calculated the space allocation status by comparing the sum of the sizes of all the allocated chunks in the dataset against the total data size of the dataset, as calculated by the number of elements in the dataset's dataspace multiplied by the dataset's datatype size. If the dataset had any compression filters applied to it and the dataset chunks were successfully compressed, the sum of the sizes of the allocated dataset chunks would generally always be less than the total data size of the dataset, and H5Dget_space_status() wouldn't ever return H5D_SPACE_STATUS_ALLOCATED.

Returns:

Returns the amount of storage space, in bytes, or 0 (zero). \details H5Dget_storage_size() returns the amount of storage, in bytes, that is allocated in the file for the raw data of the dataset specified by \p dset_id. H5Dget_storage_size() reports only the space required to store the dataset elements, excluding any metadata. \li For contiguous datasets, the returned size equals the current allocated size of the raw data. \li For unfiltered chunked datasets, the returned size is the number of allocated chunks times the chunk size. \li For filtered chunked datasets, the returned size is the space required to store the filtered data. For example, if a compression filter is in use, H5Dget_storage_size() will return the total space required to store the compressed chunks. \note Note that H5Dget_storage_size() is not generally an appropriate function to use when determining the amount of memory required to work with a dataset. In such circumstances, you must determine the number of data points in a dataset and the size of an individual dataset element. H5Sget_simple_extent_npoints() and H5Tget_size() can be used to calculate that amount. \warning H5Dget_storage_size() does not differentiate between 0 (zero), the value returned for the storage size of a dataset with no stored values, and 0 (zero), the value returned to indicate an error.

Parameters:

Returns:

\herr_t \details H5Dget_num_chunks() retrieves the number of chunks nchunks in a set of selected elements specified by \p fspace_id for a dataset specified by the identifier \p dset_id. If \p fspace_id is #H5S_ALL, the function will retrieve the total number of chunks stored for the dataset. \p fspace_id specifies the file dataspace selection. It is intended to take #H5S_ALL for specifying the current selection. \note Please be aware that this function currently does not support non-trivial selections, thus \p fspace_id has no effect. Also, the implementation does not handle the #H5S_ALL macro correctly. As a workaround, application can get the dataspace for the dataset using H5Dget_space() and pass that in for \p fspace_id. This will be fixed in a future release.

-------------------------------------------------------------------------- \ingroup H5D \brief Retrieves information about a chunk specified by its index \dset_id

Parameters:

fspace_id - [in] File dataspace selection identifier (See Note below)

chk_idx - [in] Index of the chunk

offset - [out] Logical position of the chunk’s first element in units of dataset elements

filter_mask - [out] Bitmask indicating the filters used when the chunk was written

addr - [out] Chunk address in the file

size - [out] Chunk size in bytes, 0 if the chunk does not exist

Returns:

\herr_t \details H5Dget_chunk_info() retrieves the offset coordinates, \p offset, filter mask, \p filter_mask, size, \p size, and address \p addr for the dataset specified by the identifier \p dset_id and the chunk specified by the index \p index. The chunk belongs to a set of chunks in the selection specified by \p fspace_id. If the queried chunk does not exist in the file, the size will be set to 0 and address to #HADDR_UNDEF. The value pointed to by filter_mask will not be modified. \c NULL can be passed in for any \p out parameters. \p chk_idx is the chunk index in the selection. The index value may have a value of 0 up to the number of chunks stored in the file that has a nonempty intersection with the file dataspace selection. \note As of 1.10.5, the dataspace intersection is not yet supported. Hence, the index is of all the written chunks. \p fspace_id specifies the file dataspace selection. It is intended to take #H5S_ALL to specify the current selection. \note Please be aware that this function currently does not support non-trivial selections; thus \p fspace_id has no effect. Also, the implementation does not handle the #H5S_ALL macro correctly. As a workaround, an application can get the dataspace for the dataset using H5Dget_space() and pass that in for \p fspace_id. This will be fixed in a future release.

Parameters:

mem_type_id - [in] Identifier of the memory datatype

mem_space_id - [in] Identifier of the memory dataspace

file_space_id - [in] Identifier of the dataset's dataspace in the file

dxpl_id - [in] Identifier of a transfer property list

buf - [out] Buffer to receive data read from file

Returns:

\herr_t \details H5Dread() reads a dataset, specified by its identifier \p dset_id, from the file into an application memory buffer \p buf. Data transfer properties are defined by the argument \p dxpl_id. The memory datatype of the (partial) dataset is identified by the identifier \p mem_type_id. The part of the dataset to read is defined by \p mem_space_id and \p file_space_id. \p file_space_id is used to specify only the selection within the file dataset's dataspace. Any dataspace specified in \p file_space_id is ignored by the library and the dataset's dataspace is always used. \p file_space_id can be the constant #H5S_ALL, which indicates that the entire file dataspace, as defined by the current dimensions of the dataset, is to be selected. \p mem_space_id is used to specify both the memory dataspace and the selection within that dataspace. \p mem_space_id can be the constant #H5S_ALL, in which case the file dataspace is used for the memory dataspace and the selection defined with \p file_space_id is used for the selection within that dataspace. The number of elements selected in the memory dataspace \Emph{must} be equal to the number of elements selected in the file dataspace. The behavior of the library for the various combinations of valid dataspace identifiers and #H5S_ALL for the \p mem_space_id and the \p file_space_id parameters is described below:

mem_space_id	file_space_id	Behavior
valid dataspace ID	valid dataspace ID	\p mem_space_id specifies the memory dataspace and the selection within it. \p file_space_id specifies the selection within the file dataset's dataspace.
#H5S_ALL	valid dataspace ID	The file dataset's dataspace is used for the memory dataspace and the selection specified with \p file_space_id specifies the selection within it. The combination of the file dataset's dataspace and the selection from \p file_space_id is used for memory also.
valid dataspace ID	#H5S_ALL	\p mem_space_id specifies the memory dataspace and the selection within it. The selection within the file dataset's dataspace is set to the "all" selection.
#H5S_ALL	#H5S_ALL	The file dataset's dataspace is used for the memory dataspace and the selection within the memory dataspace is set to the "all" selection. The selection within the file dataset's dataspace is set to the "all" selection.

\note If no storage space was allocated for the dataset and a fill value is defined, the returned buffer \p buf is filled with the fill value. \par Example \snippet H5D_examples.c read

Returns:

\herr_t \details H5Dread_multi() reads data from \p count datasets, whose identifiers are listed in the \p dset_id array, from the file into multiple application memory buffers listed in the \p buf array. Data transfer properties are defined by the argument \p dxpl_id. The memory datatypes of each dataset are listed by identifier in the \p mem_type_id array. The parts of each dataset to read are listed by identifier in the \p file_space_id array, and the parts of each application memory buffer to read to are listed by identifier in the \p mem_space_id array. All array parameters have length \p count. This function will produce the same results as \p count calls to H5Dread(). Information listed in that function about the specifics of its behavior also applies to H5Dread_multi(). By calling H5Dread_multi() instead of multiple calls to H5Dread(), however, the library can in some cases pass information about the entire I/O operation to the file driver, which can improve performance. All datasets must be in the same HDF5 file, and each unique dataset may only be listed once. If this function is called collectively in parallel, each rank must pass exactly the same list of datasets in \p dset_id , though the other parameters may differ.

Parameters:

dset_id - [in] Identifier of the dataset to read from

mem_type_id - [in] Identifier of the memory datatype

mem_space_id - [in] Identifier of the memory dataspace

file_space_id - [in] Identifier of the dataset's dataspace in the file \dxpl_id

buf - [out] Buffer with data to be written to the file

Returns:

\herr_t \details H5Dwrite() writes a (partial) dataset, specified by its identifier \p dset_id, from the application memory buffer \p buf into the file. Data transfer properties are defined by the argument \p dxpl_id. The memory datatype of the (partial) dataset is identified by the identifier \p mem_type_id. The part of the dataset to write is defined by \p mem_space_id and \p file_space_id. If \p mem_type_id is either a fixed-length or variable-length string, it is important to set the string length when defining the datatype. String datatypes are derived from #H5T_C_S1 (or #H5T_FORTRAN_S1 for Fortran codes), which defaults to 1 character in size. See H5Tset_size() and Creating variable-length string datatypes. \p file_space_id is used to specify only the selection within the file dataset's dataspace. Any dataspace specified in \p file_space_id is ignored by the library and the dataset's dataspace is always used. \p file_space_id can be the constant #H5S_ALL, which indicates that the entire file dataspace, as defined by the current dimensions of the dataset, is to be selected. \p mem_space_id is used to specify both the memory dataspace and the selection within that dataspace. mem_space_id can be the constant #H5S_ALL, in which case the file dataspace is used for the memory dataspace and the selection defined with \p file_space_id is used for the selection within that dataspace. The behavior of the library for the various combinations of valid dataspace IDs and #H5S_ALL for the mem_space_id and thefile_space_id parameters is described below:

\c mem_space_id	\c file_space_id	Behavior
valid dataspace ID	valid dataspace ID	\p mem_space_id specifies the memory dataspace and the selection within it. \p file_space_id specifies the selection within the file dataset's dataspace.
#H5S_ALL	valid dataspace ID	The file dataset's dataspace is used for the memory dataspace and the selection specified with \p file_space_id specifies the selection within it. The combination of the file dataset's dataspace and the selection from \p file_space_id is used for memory also. valid dataspace ID
valid dataspace ID	#H5S_ALL	\p mem_space_id specifies the memory dataspace and the selection within it. The selection within the file dataset's dataspace is set to "all" selection.
#H5S_ALL	#H5S_ALL	The file dataset's dataspace is used for the memory dataspace and the selection within the memory dataspace is set to the "all" selection. The selection within the file dataset's dataspace is set to the "all" selection.

Setting an "all" selection indicates that the entire dataspace, as defined by the current dimensions of a dataspace, will be selected. The number of elements selected in the memory dataspace must match the number of elements selected in the file dataspace. \p dxpl_id can be the constant #H5P_DEFAULT, in which case the default data transfer properties are used. Writing to a dataset will fail if the HDF5 file was not opened with write access permissions. If the dataset's space allocation time is set to #H5D_ALLOC_TIME_LATE or #H5D_ALLOC_TIME_INCR and the space for the dataset has not yet been allocated, that space is allocated when the first raw data is written to the dataset. Unused space in the dataset will be written with fill values at the same time if the dataset's fill time is set to #H5D_FILL_TIME_IFSET or #H5D_FILL_TIME_ALLOC. \par_compr_note \attention If a dataset's storage layout is 'compact', care must be taken when writing data to the dataset in parallel. A compact dataset's raw data is cached in memory and may be flushed to the file from any of the parallel processes, so parallel applications should always attempt to write identical data to the dataset from all processes. \par Example \snippet H5D_examples.c update

The parts of each dataset to write are listed by identifier in the \p file_space_id array, and the parts of each application memory buffer to write from are listed by identifier in the \p mem_space_id array. All array parameters have length \p count. This function will produce the same results as \p count calls to H5Dwrite(). Information listed in that function's documentation about the specifics of its behaviour also apply to H5Dwrite_multi(). By calling H5Dwrite_multi() instead of multiple calls to H5Dwrite(), however, the library can in some cases pass information about the entire I/O operation to the file driver, which can improve performance. All datasets must be in the same HDF5 file, and each unique dataset may only be listed once. If this function is called collectively in parallel, each rank must pass exactly the same list of datasets in \p dset_id , though the other parameters may differ.

-------------------------------------------------------------------------- \ingroup H5D \brief Writes a raw data chunk from a buffer directly to a dataset in a file \dset_id \dxpl_id

Parameters:

filters - [in] Mask for identifying the filters in use

offset - [in] Logical position of the chunk’s first element in the dataspace

data_size - [in] Size of the actual data to be written in bytes

buf - [in] Buffer containing data to be written to the chunk

Returns:

\herr_t \details H5Dwrite_chunk() writes a raw data chunk as specified by its logical offset \p offset in a chunked dataset \p dset_id from the application memory buffer \p buf to the dataset in the file. Typically, the data in \p buf is preprocessed in memory by a custom transformation, such as compression. The chunk will bypass the library’s internal data transfer pipeline, including filters, and will be written directly to the file. Only one chunk can be written with this function. \p filters is a mask providing a record of which filters are used with the chunk. The default value of the mask is zero (0), indicating that all enabled filters are applied. A filter is skipped if the bit corresponding to the filter’s position in the pipeline (0 ≤ position < 32) is turned on. This mask is saved with the chunk in the file. \p offset is an array specifying the logical position of the first element of the chunk in the dataset’s dataspace. The length of the offset array must equal the number of dimensions, or rank, of the dataspace. The values in offset must not exceed the dimension limits and must specify a point that falls on a dataset chunk boundary. \p data_size is the size in bytes of the chunk, representing the number of bytes to be read from the buffer \p buf. If the data chunk has been precompressed, \p data_size should be the size of the compressed data. \p buf is the memory buffer containing data to be written to the chunk in the file. \attention Exercise caution when using H5Dread_chunk() and H5Dwrite_chunk(), as they read and write data chunks directly in a file. H5Dwrite_chunk() bypasses hyperslab selection, the conversion of data from one datatype to another, and the filter pipeline to write the chunk. Developers should have experience with these processes before using this function. \note H5Dread_chunk() and H5Dwrite_chunk() are currently not supported with parallel HDF5 and do not support variable-length types.

If \p fill is NULL, a fill value of 0 (zero) is used. \p fill_type_id specifies the datatype of the fill value. \p buf specifies the buffer in which the fill elements will be written. \p buf_type_id specifies the datatype of those data elements. \note Note that if the fill value datatype differs from the memory buffer datatype, the fill value will be converted to the memory buffer datatype before filling the selection. \note Applications sometimes write data only to portions of an allocated dataset. It is often useful in such cases to fill the unused space with a known fill value.

Space on disk is immediately allocated for the new dataset extent if the dataset’s space allocation time is set to #H5D_ALLOC_TIME_EARLY. Fill values will be written to the dataset in either of the following situations, but not otherwise: - If the dataset’s fill time is set to #H5D_FILL_TIME_IFSET and a fill value is defined (see H5Pset_fill_time() and H5Pset_fill_value()) - If the dataset’s fill time is set to #H5D_FILL_TIME_ALLOC (see H5Pset_alloc_time()) \note If the sizes specified in \p size array are smaller than the dataset’s current dimension sizes, H5Dset_extent() will reduce the dataset’s dimension sizes to the specified values. It is the user application’s responsibility to ensure that valuable data is not lost as H5Dset_extent() does not check. \note Except for external datasets, H5Dset_extent() is for use with chunked datasets only, not contiguous datasets. \note A call to H5Dset_extent() affects the dataspace of a dataset. If a dataspace handle was opened for a dataset prior to a call to H5Dset_extent() then that dataspace handle will no longer reflect the correct dataspace extent of the dataset. H5Dget_space() must be called (after closing the previous handle) to obtain the current dataspace extent.

dst_buf_size - [in] Size in bytes of \p dst_buf

dst_buf - [out] Destination buffer for the gathered data

op - [in] Callback function which handles the gathered data

op_data - [in] User-defined pointer to data required by \p op

Returns:

\herr_t \details H5Dgather() retrieves data from a selection within the supplied buffer src_buf and passes it to the supplied callback function \p op in a contiguous form. The dataspace \p src_space_id describes both the dimensions of the source buffer and the selection within the source buffer to gather data from. \p src_buf must be at least the size of the gathered data, that is, the number of elements in the extent of \p src_space_id times the size in bytes of \p type_id. The datatype \p type_id describes the data in both the source and destination buffers. This information is used to calculate the element size. The data is gathered into \p dst_buf, which needs to be large enough to hold all the data if the callback function \p op is not provided. \p op is a callback function that handles the gathered data. It is optional if \p dst_buf is large enough to hold all of the gathered data; required otherwise. If no callback function is provided, H5Dgather() simply gathers the data into \p dst_buf and returns. If a callback function is provided, H5Dgather() repeatedly gathers up to \p dst_buf_size bytes to process the serialized data. The callback function \p op should process, store, or otherwise, make use of the data returned in \p dst_buf before it returns, because the buffer will be overwritten unless it is the last call to the callback. This function will be repeatedly called until all gathered elements have been passed to the callback in \p dst_buf. The callback function should return zero (0) to indicate success, and a negative value to indicate failure.

Parameters:

func - [in] Function to be called for each error encountered

client_data - [in] Data to be passed to \p func

Returns:

\herr_t \details H5Ewalk2() walks the error stack specified by err_stack for the current thread and calls the function specified in \p func for each error along the way. If the value of \p err_stack is #H5E_DEFAULT, then H5Ewalk2() walks the current error stack. \p direction specifies whether the stack is walked from the inside out or the outside in. A value of #H5E_WALK_UPWARD means to begin with the most specific error and end at the API; a value of #H5E_WALK_DOWNWARD means to start at the API and end at the innermost function where the error was first detected. \p func, a function conforming to the #H5E_walk2_t prototype, will be called for each error in the error stack. Its arguments will include an index number \c n (beginning at zero regardless of stack traversal direction), an error stack entry \c err_desc, and the \c client_data pointer passed to H5Eprint().

-------------------------------------------------------------------------- \ingroup H5E \brief Returns the settings for the automatic error stack traversal function and its data \estack_id

Parameters:

func - [out] The function currently set to be called upon an error condition

client_data - [out] Data currently set to be passed to the error function

Returns:

\herr_t \details H5Eget_auto2() returns the settings for the automatic error stack traversal function, \p func, and its data, \p client_data, that are associated with the error stack specified by \p estack_id. Either or both of the \p func and \p client_data arguments may be \c NULL, in which case the value is not returned. The library initializes its default error stack traversal functions to H5Eprint1() and H5Eprint2(). A call to H5Eget_auto2() returns H5Eprint2() or the user-defined function passed in through H5Eset_auto2(). A call to H5Eget_auto1() returns H5Eprint1() or the user-defined function passed in through H5Eset_auto1(). However, if the application passes in a user-defined function through H5Eset_auto1(), it should call H5Eget_auto1() to query the traversal function. If the application passes in a user-defined function through H5Eset_auto2(), it should call H5Eget_auto2() to query the traversal function. Mixing the new style and the old style functions will cause a failure. For example, if the application sets a user-defined old-style traversal function through H5Eset_auto1(), a call to H5Eget_auto2() will fail and will indicate that the application has mixed H5Eset_auto1() and H5Eget_auto2(). On the other hand, mixing H5Eset_auto2() and H5Eget_auto1() will also cause a failure. But if the traversal functions are the library’s default H5Eprint1() or H5Eprint2(), mixing H5Eset_auto1() and H5Eget_auto2() or mixing H5Eset_auto2() and H5Eget_auto1() does not fail.

Parameters:

filename - [in] Name of the file to create

flags - [in] File access flags. Allowable values are: - #H5F_ACC_TRUNC: Truncate file, if it already exists, erasing all data previously stored in the file - #H5F_ACC_EXCL: Fail if file already exists \fcpl_id \fapl_id

Returns:

\hid_t{file} \details H5Fcreate() is the primary function for creating HDF5 files; it creates a new HDF5 file with the specified name and property lists. The \p filename parameter specifies the name of the new file. The \p flags parameter specifies whether an existing file is to be overwritten. It should be set to either #H5F_ACC_TRUNC to overwrite an existing file or #H5F_ACC_EXCL, instructing the function to fail if the file already exists. New files are always created in read-write mode, so the read-write and read-only flags, #H5F_ACC_RDWR and #H5F_ACC_RDONLY, respectively, are not relevant in this function. Further note that a specification of #H5F_ACC_RDONLY will be ignored; the file will be created in read-write mode, regardless. More complex behaviors of file creation and access are controlled through the file creation and file access property lists, \p fcpl_id and \p fapl_id, respectively. The value of #H5P_DEFAULT for any property list value indicates that the library should use the default values for that appropriate property list. The return value is a file identifier for the newly-created file; this file identifier should be closed by calling H5Fclose() when it is no longer needed. \par Example \snippet H5F_examples.c minimal \note #H5F_ACC_TRUNC and #H5F_ACC_EXCL are mutually exclusive; use exactly one. \note An additional flag, #H5F_ACC_DEBUG, prints debug information. This flag can be combined with one of the above values using the bit-wise OR operator (\c |), but it is used only by HDF5 library developers; \Emph{it is neither tested nor supported for use in applications}. \attention \Bold{Special case — File creation in the case of an already-open file:} If a file being created is already opened, by either a previous H5Fopen() or H5Fcreate() call, the HDF5 library may or may not detect that the open file and the new file are the same physical file. (See H5Fopen() regarding the limitations in detecting the re-opening of an already-open file.)\n If the library detects that the file is already opened, H5Fcreate() will return a failure, regardless of the use of #H5F_ACC_TRUNC.\n If the library does not detect that the file is already opened and #H5F_ACC_TRUNC is not used, H5Fcreate() will return a failure because the file already exists. Note that this is correct behavior.\n But if the library does not detect that the file is already opened and #H5F_ACC_TRUNC is used, H5Fcreate() will truncate the existing file and return a valid file identifier. Such a truncation of a currently-opened file will almost certainly result in errors. While unlikely, the HDF5 library may not be able to detect, and thus report, such errors.\n Applications should avoid calling H5Fcreate() with an already opened file.

\ingroup H5F \brief Opens an existing HDF5 file

Parameters:

filename - [in] Name of the file to be opened

flags - [in] File access flags. Allowable values are: - #H5F_ACC_RDWR: Allows read and write access to file - #H5F_ACC_RDONLY: Allows read-only access to file - #H5F_ACC_RDWR \c | #H5F_ACC_SWMR_WRITE: Indicates that the file is open for writing in a single-writer/multi-writer (SWMR) scenario. - #H5F_ACC_RDONLY \c | #H5F_ACC_SWMR_READ: Indicates that the file is open for reading in a single-writer/multi-reader (SWMR) scenario. - An additional flag, #H5F_ACC_DEBUG, prints debug information. This flag can be combined with one of the above values using the bit-wise OR operator (\c |), but it is used only by HDF5 library developers; \Emph{it is neither tested nor supported} for use in applications. \fapl_id

Returns:

\hid_t{file} \details H5Fopen() is the primary function for accessing existing HDF5 files. This function opens the named file in the specified access mode and with the specified access property list. Note that H5Fopen() does not create a file if it does not already exist; see H5Fcreate(). The \p filename parameter specifies the name of the file to be opened. The \p fapl_id parameter specifies the file access property list. The use of #H5P_DEFAULT specifies that default I/O access properties are to be used. The \p flags parameter specifies whether the file will be opened in read-write or read-only mode, #H5F_ACC_RDWR or #H5F_ACC_RDONLY, respectively. More complex behaviors of file access are controlled through the file-access property list. The return value is a file identifier for the open file; this file identifier should be closed by calling H5Fclose() when it is no longer needed. \par Example \snippet H5F_examples.c open \note #H5F_ACC_RDWR and #H5F_ACC_RDONLY are mutually exclusive; use exactly one. \attention \Bold{Special cases — Multiple opens:} A file can often be opened with a new H5Fopen() call without closing an already-open identifier established in a previous H5Fopen() or H5Fcreate() call. Each such H5Fopen() call will return a unique identifier and the file can be accessed through any of these identifiers as long as the identifier remains valid. In such multiply-opened cases, the open calls must use the same flags argument and the file access property lists must use the same file close degree property setting (see the external link discussion below and H5Pset_fclose_degree()).\n In some cases, such as files on a local Unix file system, the HDF5 library can detect that a file is multiply opened and will maintain coherent access among the file identifiers.\n But in many other cases, such as parallel file systems or networked file systems, it is not always possible to detect multiple opens of the same physical file. In such cases, HDF5 will treat the file identifiers as though they are accessing different files and will be unable to maintain coherent access. Errors are likely to result in these cases. While unlikely, the HDF5 library may not be able to detect, and thus report, such errors.\n It is generally recommended that applications avoid multiple opens of the same file. \attention \Bold{Special restriction on multiple opens of a file first opened by means of an external link:} When an external link is followed, the external file is always opened with the weak file close degree property setting, #H5F_CLOSE_WEAK (see H5Lcreate_external() and H5Pset_fclose_degree()). If the file is reopened with H5Fopen while it remains held open from such an external link call, the file access property list used in the open call must include the file close degree setting #H5F_CLOSE_WEAK or the open will fail.

\ingroup H5F \brief Terminates access to an HDF5 file \file_id

Returns:

\herr_t \details H5Fclose() terminates access to an HDF5 file (specified by \p file_id) by flushing all data to storage. If this is the last file identifier open for the file and no other access identifier is open (e.g., a dataset identifier, group identifier, or shared datatype identifier), the file will be fully closed and access will end. \par Example \snippet H5F_examples.c minimal \note \Bold{Delayed close:} Note the following deviation from the above-described behavior. If H5Fclose() is called for a file, but one or more objects within the file remain open, those objects will remain accessible until they are individually closed. Thus, if the dataset \c data_sample is open when H5Fclose() is called for the file containing it, \c data_sample will remain open and accessible (including writable) until it is explicitly closed. The file will be automatically closed once all objects in the file have been closed.\n Be warned, however, that there are circumstances where it is not possible to delay closing a file. For example, an MPI-IO file close is a collective call; all of the processes that open the file must close it collectively. The file cannot be closed at some time in the future by each process in an independent fashion. Another example is that an application using an AFS token-based file access privilege may destroy its AFS token after H5Fclose() has returned successfully. This would make any future access to the file, or any object within it, illegal.\n In such situations, applications must close all open objects in a file before calling H5Fclose. It is generally recommended to do so in all cases.

\ingroup H5F \brief Deletes an HDF5 file

Parameters:

filename - [in] Name of the file to delete \fapl_id

Returns:

\herr_t \details H5Fdelete() deletes an HDF5 file \p filename with a file access property list \p fapl_id. The \p fapl_id should be configured with the same VOL connector or VFD that was used to open the file. This API was introduced for use with the Virtual Object Layer (VOL). With the VOL, HDF5 "files" can map to arbitrary storage schemes such as object stores and relational database tables. The data created by these implementations may be inconvenient for a user to remove without a detailed knowledge of the storage scheme. H5Fdelete() gives VOL connector authors the ability to add connector-specific delete code to their connectors so that users can remove these "files" without detailed knowledge of the storage scheme. For a VOL connector, H5Fdelete() deletes the file in a way that makes sense for the specified VOL connector. For the native HDF5 connector, HDF5 files will be deleted via the VFDs, each of which will have to be modified to delete the files it creates. For all implementations, H5Fdelete() will first check if the file is an HDF5 file via H5Fis_accessible(). This is done to ensure that H5Fdelete() cannot be used as an arbitrary file deletion call.

Returns:

Returns the amount of free space in the file if successful; otherwise returns a negative value. \details Given the identifier of an open file, \p file_id, H5Fget_freespace() returns the amount of space that is unused by any objects in the file. The interpretation of this number depends on the configured free space management strategy. For example, if the HDF5 library only tracks free space in a file from a file open or create until that file is closed, then this routine will report the free space that has been created during that interval.

Parameters:

buf_ptr - [out] Pointer to the buffer into which the image of the HDF5 file is to be copied. If \p buf_ptr is NULL, no data will be copied but the function’s return value will still indicate the buffer size required (or a negative value on error).

buf_len - [out] Size of the supplied buffer

Returns:

ssize_t \details H5Fget_file_image() retrieves a copy of the image of an existing, open file. This routine can be used with files opened using the SEC2 (or POSIX), STDIO, and Core (or Memory) virtual file drivers (VFDs). If the return value of H5Fget_file_image() is a positive value, it will be the length in bytes of the buffer required to store the file image. So if the file size is unknown, it can be safely determined with an initial H5Fget_file_image() call with buf_ptr set to NULL. The file image can then be retrieved with a second H5Fget_file_image() call with \p buf_len set to the initial call’s return value. While the current file size can also be retrieved with H5Fget_filesize(), that call may produce a larger value than is needed. The value returned by H5Fget_filesize() includes the user block, if it exists, and any unallocated space at the end of the file. It is safe in all situations to get the file size with H5Fget_file_image() and it often produces a value that is more appropriate for the size of a file image buffer. \note \Bold{Recommended Reading:} This function is part of the file image operations feature set. It is highly recommended to study the guide \ref_file_image_ops before using this feature set. \attention H5Pget_file_image() will fail, returning a negative value, if the file is too large for the supplied buffer.

size - [in] Size, in bytes, of the \p name buffer

Returns:

Returns the length of the file name if successful; otherwise returns a negative value. \details H5Fget_name() retrieves the name of the file to which the object \p obj_id belongs. The object can be a file, group, dataset, attribute, or named datatype. Up to \p size characters of the file name are returned in \p name; additional characters, if any, are not returned to the user application. If the length of the name, which determines the required value of size, is unknown, a preliminary H5Fget_name() call can be made by setting \p name to NULL. The return value of this call will be the size of the file name; that value plus one (1) can then be assigned to size for a second H5Fget_name() call, which will retrieve the actual name. (The value passed in with the parameter \p size must be one greater than size in bytes of the actual name in order to accommodate the null terminator; if \p size is set to the exact size of the name, the last byte passed back will contain the null terminator and the last character will be missing from the name passed back to the calling application.) If an error occurs, the buffer pointed to by \p name is unchanged and the function returns a negative value.

This information is reported in the H5F_retry_info_t struct defined in H5Fpublic.h as follows: \snippet this H5F_retry_info_t_snip \c nbins is the number of bins for each \c retries[i] of metadata entry \c i. It is calculated based on the current number of read attempts used in the library and logarithmic base 10. If read retries are incurred for a metadata entry \c i, the library will allocate memory for \Code{retries[i] (nbins * sizeof(uint32_t)} and store the collection of retries there. If there are no retries for a metadata entry \c i, \Code{retries[i]} will be NULL. After a call to this routine, users should free each \Code{retries[i]} that is non-NULL, otherwise resource leak will occur. For the library default read attempts of 100 for SWMR access, nbins will be 2 as depicted below: \li \Code{retries[i][0]} is the number of 1 to 9 read retries. \li \Code{retries[i][1]} is the number of 10 to 99 read retries. For the library default read attempts of 1 for non-SWMR access, \c nbins will be 0 and each \Code{retries[i]} will be NULL. The following table lists the 21 metadata entries of \Code{retries[]}:

Index for \Code{retries[]}	Metadata entries*
0	Object header (version 2)
1	Object header chunk (version 2)
2	B-tree header (version 2)
3	B-tree internal node (version 2)
4	B-tree leaf node (version 2)
5	Fractal heap header
6	Fractal heap direct block (optional checksum)
7	Fractal heap indirect block

20	File's superblock (version 2)
* All entries are of version 0 (zero) unless indicated otherwise.

\note On a system that is not atomic, the library might possibly read inconsistent metadata with checksum when performing single-writer/multiple-reader (SWMR) operations for an HDF5 file. Upon encountering such situations, the library will try reading the metadata again for a set number of times to attempt to obtain consistent data. The maximum number of read attempts used by the library will be either the value set via H5Pset_metadata_read_attempts() or the library default value when a value is not set.\n When the current number of metadata read attempts used in the library is unable to remedy the reading of inconsistent metadata on a system, the user can assess the information obtained via this routine to derive a different maximum value. The information can also be helpful for debugging purposes to identify potential issues with metadata flush dependencies and SWMR implementation in general.

Library objects are groups, datasets, and committed datatypes. For the current implementation, groups and datasets can remain open when activating SWMR writing mode, but not committed datatypes. Attributes attached to objects cannot remain open either.

Returns:

\herr_t \details \parblock H5Fget_mdc_image_info() returns information about a cache image if it exists. When an HDF5 file is opened in Read/Write mode, any metadata cache image will be read and deleted from the file on the first metadata cache access (or, if persistent free space managers are enabled, on the first file space allocation / deallocation, or read of free space manager status, whichever comes first). Thus, if the file is opened Read/Write, H5Fget_mdc_image_info() should be called immediately after file open and before any other operation. If H5Fget_mdc_image_info() is called after the cache image is loaded, it will correctly report that no cache image exists, as the image will have already been read and deleted from the file. In the Read Only case, the function may be called at any time, as any cache image will not be deleted from the file. \endparblock

By setting the \p minimize flag to \c TRUE, the library expects that no attributes will be added to the dataset - attributes can be added, but they are appended with a continuation message, which can reduce performance. \attention This setting interacts with H5Pset_dset_no_attrs_hint(): if either is set to \c TRUE, then the created dataset's object header will be minimized.

\hid_t{group} \details H5Gcreate2() creates a new group in a file. After a group has been created, links to datasets and to other groups can be added. The \p loc_id and \p name parameters specify where the group is located. \p loc_id may be a file, group, dataset, named datatype or attribute in the file. If an attribute, dataset, or named datatype is specified for \p loc_id then the group will be created at the location where the attribute, dataset, or named datatype is attached. \p name is the link to the group; \p name may be either an absolute path in the file (the links from the root group to the new group) or a relative path from \p loc_id (the link(s) from the group specified by \p loc_id to the new group). \p lcpl_id, \p gcpl_id, and \p gapl_id are property list identifiers. These property lists govern how the link to the group is created, how the group is created, and how the group can be accessed in the future, respectively. #H5P_DEFAULT can be passed in if the default properties are appropriate for these property lists. Currently, there are no APIs for the group access property list; use #H5P_DEFAULT. The group identifier should be closed by H5Gclose() when access is no longer required to prevent resource leaks.

Returns:

\hid_t{group} \details H5Gcreate_anon() creates a new empty group in the file specified by \p loc_id. With default settings, H5Gcreate_anon() provides similar functionality to that provided by H5Gcreate1(), with the differences described in the list below. The new group’s creation and access properties are specified in \p gcpl_id and \p gapl_id, respectively. H5Gcreate_anon() returns a new group identifier. This identifier must be linked into the HDF5 file structure with H5Olink() or it will be deleted from the file when the file is closed. The differences between this function and H5Gcreate1() are as follows: \li H5Gcreate1() does not provide for the use of custom property lists; H5Gcreate1() always uses default properties. \li H5Gcreate_anon() neither provides the new group’s name nor links it into the HDF5 file structure; those actions must be performed separately through a call to H5Olink(), which offers greater control over linking. \li H5Gcreate_anon() does not directly provide a hint mechanism for the group’s heap size. Comparable information can be included in the group creation property list \p gcpl_id through a H5Pset_local_heap_size_hint() call. A group created with this function should be closed with H5Gclose() when the group is no longer needed so that resource leaks will not develop.

Parameters:

dst_id - [in] Identifier of the destination property list or class

src_id - [in] Identifier of the source property list or class

name - [in] Name of the property to copy

Returns:

\herr_t \details H5Pcopy_prop() copies a property from one property list or class to another. If a property is copied from one class to another, all the property information will be first deleted from the destination class and then the property information will be copied from the source class into the destination class. If a property is copied from one list to another, the property will be first deleted from the destination list (generating a call to the close callback for the property, if one exists) and then the property is copied from the source list to the destination list (generating a call to the copy callback for the property, if one exists). If the property does not exist in the class or list, this call is equivalent to calling H5Pregister() or H5Pinsert() (for a class or list, as appropriate) and the create callback will be called in the case of the property being copied into a list (if such a callback exists for the property).

create - [in] Callback routine called when a property list is created

create_data - [in] Pointer to user-defined class create data, to be passed along to class create callback

copy - [in] Callback routine called when a property list is copied

Returns:

\hid_t{property list class} \details H5Pcreate_class() registers a new property list class with the library. The new property list class can inherit from an existing property list class, \p parent, or may be derived from the default “empty” class, NULL. New classes with inherited properties from existing classes may not remove those existing properties, only add or remove their own class properties. Property list classes defined and supported in the HDF5 library distribution are listed and briefly described in H5Pcreate(). The \p create, \p copy, \p close functions are called when a property list of the new class is created, copied, or closed, respectively. H5Pclose_class() must be used to release the property list class identifier returned by this function.

Parameters:

Returns:

\hid_tv{object} \details Given a binary property list description in a buffer, H5Pdecode() reconstructs the HDF5 property list and returns an identifier for the new property list. The binary description of the property list is encoded by H5Pencode(). The user is responsible for passing in the correct buffer. The property list identifier returned by this function should be released with H5Pclose() when the identifier is no longer needed so that resource leaks will not develop. \note Some properties cannot be encoded and therefore will not be available in the decoded property list. These properties are discussed in H5Pencode().

\ingroup PLCR \brief Encodes the property values in a property list into a binary buffer \plist_id

Parameters:

buf - [out] Buffer into which the property list will be encoded. If the provided buffer is NULL, the size of the buffer required is returned through \p nalloc; the function does nothing more.

nalloc - [out] The size of the required buffer \fapl_id

Returns:

\herr_t \details H5Pencode2() encodes the property list \p plist_id into the binary buffer \p buf, according to the file format setting specified by the file access property list \p fapl_id. If the required buffer size is unknown, \p buf can be passed in as NULL and the function will set the required buffer size in \p nalloc. The buffer can then be created and the property list encoded with a subsequent H5Pencode2() call. If the buffer passed in is not big enough to hold the encoded properties, the H5Pencode2() call can be expected to fail with a segmentation fault. The file access property list \p fapl_id is used to control the encoding via the \a libver_bounds property (see H5Pset_libver_bounds()). If the \a libver_bounds property is missing, H5Pencode2() proceeds as if the \a libver_bounds property were set to (#H5F_LIBVER_EARLIEST, #H5F_LIBVER_LATEST). (Functionally, H5Pencode1() is identical to H5Pencode2() with \a libver_bounds set to (#H5F_LIBVER_EARLIEST, #H5F_LIBVER_LATEST).) Properties that do not have encode callbacks will be skipped. There is currently no mechanism to register an encode callback for a user-defined property, so user-defined properties cannot currently be encoded. Some properties cannot be encoded, particularly properties that are reliant on local context. \b Motivation: This function was introduced in HDF5-1.12 as part of the \a H5Sencode format change to enable 64-bit selection encodings and a dataspace selection that is tied to a file.

\ingroup PLCR \brief Returns the property list class identifier for a property list \plist_id

Returns:

\hid_t{property list class} \details H5Pget_class() returns the property list class identifier for the property list identified by the \p plist_id parameter. Note that H5Pget_class() returns a value of #hid_t type, an internal HDF5 identifier, rather than directly returning a property list class. That identifier can then be used with either H5Pequal() or H5Pget_class_name() to determine which predefined HDF5 property list class H5Pget_class() has returned. A full list of valid predefined property list classes appears in the description of H5Pcreate(). Determining the HDF5 property list class name with H5Pequal() requires a series of H5Pequal() calls in an if-else sequence. An iterative sequence of H5Pequal() calls can compare the identifier returned by H5Pget_class() to members of the list of valid property list class names. A pseudo-code snippet might read as follows:

          plist_class_id = H5Pget_class (dsetA_plist);

          if H5Pequal (plist_class_id, H5P_OBJECT_CREATE) = TRUE;
              [ H5P_OBJECT_CREATE is the property list class    ]
              [ returned by H5Pget_class.                        ]

          else if H5Pequal (plist_class_id, H5P_DATASET_CREATE) = TRUE;
              [ H5P_DATASET_CREATE is the property list class.  ]

          else if H5Pequal (plist_class_id, H5P_DATASET_XFER) = TRUE;
              [ H5P_DATASET_XFER is the property list class.    ]

          .
          .   [ Continuing the iteration until a match is found. ]
          .
          

H5Pget_class_name() returns the property list class name directly as a string:

          plist_class_id = H5Pget_class (dsetA_plist);
          plist_class_name = H5Pget_class_name (plist_class_id)
          

Note that frequent use of H5Pget_class_name() can become a performance problem in a high-performance environment. The H5Pequal() approach is generally much faster.

The #H5P_prp_set_func_t callback function is defined as follows: \snippet this H5P_prp_cb2_t_snip The parameters to the callback function are defined as follows:

\ref hid_t \c prop_id	IN: The identifier of the property list being modified
\Code{const char * name}	IN: The name of the property being modified
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN: Pointer to new value pointer for the property being modified

The \p set routine may modify the value pointer to be set and those changes will be used when setting the property's value. If the \p set routine returns a negative value, the new property value is not copied into the property and the \p set routine returns an error value. The \p set routine will be called for the initial value. \b Note: The \p set callback function may be useful to range check the value being set for the property or may perform some transformation or translation of the value set. The \p get callback would then reverse the transformation or translation. A single \p get or \p set callback could handle multiple properties by performing different actions based on the property name or other properties in the property list. The \p get routine is called when a value is retrieved from a property value. The #H5P_prp_get_func_t callback function is defined as follows: \snippet this H5P_prp_cb2_t_snip The parameters to the above callback function are:

\ref hid_t \c prop_id	IN: The identifier of the property list being queried
\Code{const char * name}	IN: The name of the property being queried
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN: The value of the property being returned

The \p get routine may modify the value to be returned from the query and those changes will be preserved. If the \p get routine returns a negative value, the query routine returns an error value. The \p prp_del routine is called when a property is being deleted from a property list. The #H5P_prp_delete_func_t callback function is defined as follows: \snippet this H5P_prp_cb2_t_snip The parameters to the above callback function are:

\ref hid_t \c prop_id	IN: The identifier of the property list the property is being deleted from
\Code{const char * name}	IN: The name of the property in the list
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN: The value for the property being deleted

The \p prp_del routine may modify the value passed in, but the value is not used by the library when the \p prp_del routine returns. If the \p prp_del routine returns a negative value, the property list \p prp_del routine returns an error value but the property is still deleted. The \p copy routine is called when a new property list with this property is being created through a \p copy operation. The #H5P_prp_copy_func_t callback function is defined as follows: \snippet this H5P_prp_cb1_t_snip The parameters to the above callback function are:

\Code{const char * name}	IN: The name of the property being copied
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN/OUT: The value for the property being copied

The \p copy routine may modify the value to be set and those changes will be stored as the new value of the property. If the \p copy routine returns a negative value, the new property value is not copied into the property and the copy routine returns an error value. The \p compare routine is called when a property list with this property is compared to another property list with the same property. The #H5P_prp_compare_func_t callback function is defined as follows: \snippet this H5P_prp_compare_func_t_snip The parameters to the callback function are defined as follows:

\Code{const void * value1}	IN: The value of the first property to compare
\Code{const void * value2}	IN: The value of the second property to compare
\Code{size_t size}	IN: The size of the property in bytes

The \p compare routine may not modify the values. The \p compare routine should return a positive value if \p value1 is greater than \p value2, a negative value if \p value2 is greater than \p value1 and zero if \p value1 and \p value2 are equal. The \p close routine is called when a property list with this property is being closed. The #H5P_prp_close_func_t callback function is defined as follows: \snippet this H5P_prp_cb1_t_snip The parameters to the callback function are defined as follows:

\Code{const char * name}	IN: The name of the property in the list
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN: The value for the property being closed

The \p close routine may modify the value passed in, the value is not used by the library when the close routine returns. If the \p close routine returns a negative value, the property list \p close routine returns an error value but the property list is still closed. \b Note: There is no \p create callback routine for temporary property list objects; the initial value is assumed to have any necessary setup already performed on it.

\ingroup PLCRA \brief Iterates over properties in a property class or list

Parameters:

id - [in] Identifier of property object to iterate over

idx - [in,out] Index of the property to begin with

iter_func - [in] Function pointer to function to be called with each property iterated over

iter_data - [in,out] Pointer to iteration data from user

Returns:

On success: the return value of the last call to \p iter_func if it was non-zero; zero if all properties have been processed. On Failure, a negative value \details H5Piterate() iterates over the properties in the property object specified in \p id, which may be either a property list or a property class, performing a specified operation on each property in turn. For each property in the object, \p iter_func and the additional information specified below are passed to the #H5P_iterate_t operator function. The iteration begins with the \p idx-th property in the object; the next element to be processed by the operator is returned in \p idx. If \p idx is NULL, the iterator starts at the first property; since no stopping point is returned in this case, the iterator cannot be restarted if one of the calls to its operator returns non-zero. The operation \p iter_func receives the property list or class identifier for the object being iterated over, \p id, the name of the current property within the object, \p name, and the pointer to the operator data passed in to H5Piterate(), \p iter_data. H5Piterate() assumes that the properties in the object identified by \p id remain unchanged through the iteration. If the membership changes during the iteration, the function's behavior is undefined.

Returns:

\herr_t \details H5Pregister2() registers a new property with a property list class. The \p cls_id identifier can be obtained by calling H5Pcreate_class(). The property will exist in all property list objects of \p cl_id created after this routine finishes. The name of the property must not already exist, or this routine will fail. The default property value must be provided and all new property lists created with this property will have the property value set to the default value. Any of the callback routines may be set to NULL if they are not needed. Zero-sized properties are allowed and do not store any data in the property list. These may be used as flags to indicate the presence or absence of a particular piece of information. The default pointer for a zero-sized property may be set to NULL. The property \p create and \p close callbacks are called for zero-sized properties, but the \p set and \p get callbacks are never called. The \p create routine is called when a new property list with this property is being created. The #H5P_prp_create_func_t callback function is defined as follows: \snippet this H5P_prp_cb1_t_snip The parameters to this callback function are defined as follows:

\Code{const char * name}	IN: The name of the property being modified
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN/OUT: The default value for the property being created, which will be passed to H5Pregister2()

The \p create routine may modify the value to be set and those changes will be stored as the initial value of the property. If the \p create routine returns a negative value, the new property value is not copied into the property and the \p create routine returns an error value. The \p set routine is called before a new value is copied into the property. The #H5P_prp_set_func_t callback function is defined as follows: \snippet this H5P_prp_cb2_t_snip The parameters to this callback function are defined as follows:

\ref hid_t \c prop_id	IN: The identifier of the property list being modified
\Code{const char * name}	IN: The name of the property being modified
\Code{size_t size}	IN: The size of the property in bytes
\Code{void *value}	IN/OUT: Pointer to new value pointer for the property being modified

The \p set routine may modify the value pointer to be set and those changes will be used when setting the property's value. If the \p set routine returns a negative value, the new property value is not copied into the property and the \p set routine returns an error value. The \p set routine will not be called for the initial value; only the \p create routine will be called. \b Note: The \p set callback function may be useful to range check the value being set for the property or may perform some transformation or translation of the value set. The \p get callback would then reverse the transformation or translation. A single \p get or \p set callback could handle multiple properties by performing different actions based on the property name or other properties in the property list. The \p get routine is called when a value is retrieved from a property value. The #H5P_prp_get_func_t callback function is defined as follows: \snippet this H5P_prp_cb2_t_snip The parameters to the callback function are defined as follows:

\Code{const char * name}	IN: The name of the property being queried
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN/OUT: The value of the property being returned

The \p get routine may modify the value to be returned from the query and those changes will be returned to the calling routine. If the \p set routine returns a negative value, the query routine returns an error value. The \p prp_del routine is called when a property is being deleted from a property list. The #H5P_prp_delete_func_t callback function is defined as follows: \snippet this H5P_prp_cb2_t_snip The parameters to the callback function are defined as follows:

\ref hid_t \c prop_id	IN: The identifier of the property list the property is being deleted from
\Code{const char * name}	IN: The name of the property in the list
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN: The value for the property being deleted

The \p prp_del routine may modify the value passed in, but the value is not used by the library when the \p prp_del routine returns. If the \p prp_del routine returns a negative value, the property list delete routine returns an error value but the property is still deleted. The \p copy routine is called when a new property list with this property is being created through a \p copy operation. The #H5P_prp_copy_func_t callback function is defined as follows: \snippet this H5P_prp_cb1_t_snip The parameters to the callback function are defined as follows:

\Code{const char * name}	IN: The name of the property being copied
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN/OUT: The value for the property being copied

The \p copy routine may modify the value to be set and those changes will be stored as the new value of the property. If the \p copy routine returns a negative value, the new property value is not copied into the property and the \p copy routine returns an error value. The \p compare routine is called when a property list with this property is compared to another property list with the same property. The #H5P_prp_compare_func_t callback function is defined as follows: \snippet this H5P_prp_compare_func_t_snip The parameters to the callback function are defined as follows:

\Code{const void * value1}	IN: The value of the first property to compare
\Code{const void * value2}	IN: The value of the second property to compare
\Code{size_t size}	IN: The size of the property in bytes

The \p compare routine may not modify the values. The \p compare routine should return a positive value if \p value1 is greater than \p value2, a negative value if \p value2 is greater than \p value1 and zero if \p value1 and \p value2 are equal. The \p close routine is called when a property list with this property is being closed. The #H5P_prp_close_func_t callback function is defined as follows: \snippet this H5P_prp_cb1_t_snip The parameters to the callback function are defined as follows:

\Code{const char * name}	IN: The name of the property in the list
\Code{size_t size}	IN: The size of the property in bytes
\Code{void * value}	IN: The value for the property being closed

The \p close routine may modify the value passed in, but the value is not used by the library when the \p close routine returns. If the \p close routine returns a negative value, the property list close routine returns an error value but the property list is still closed.

\ingroup PLCRA \brief Removes a property from a property list \plist_id

Parameters:

name - [in] Name of property to remove

Returns:

\herr_t \details H5Premove() removes a property from a property list. Both properties which were in existence when the property list was created (i.e. properties registered with H5Pregister()) and properties added to the list after it was created (i.e. added with H5Pinsert1() may be removed from a property list. Properties do not need to be removed from a property list before the list itself is closed; they will be released automatically when H5Pclose() is called. If a \p close callback exists for the removed property, it will be called before the property is released.

Parameters:

name - [in] Name of property to modify

value - [in] Pointer to value to set the property to

Returns:

\herr_t \details H5Pset() sets a new value for a property in a property list. If there is a \p set callback routine registered for this property, the \p value will be passed to that routine and any changes to the \p value will be used when setting the property value. The information pointed to by the \p value pointer (possibly modified by the \p set callback) is copied into the property list value and may be changed by the application making the H5Pset() call without affecting the property value. The property name must exist or this routine will fail. If the \p set callback routine returns an error, the property value will not be modified. This routine may not be called for zero-sized properties and will return an error in that case.

Parameters:

min_dense - [out] Minimum number of attributes to be stored in dense storage (Default: 6)

Returns:

\herr_t \details H5Pget_attr_phase_change() retrieves threshold values for attribute storage on an object. These thresholds determine the point at which attribute storage changes from compact storage (i.e., storage in the object header) to dense storage (i.e., storage in a heap and indexed with a B-tree). In the general case, attributes are initially kept in compact storage. When the number of attributes exceeds \p max_compact, attribute storage switches to dense storage. If the number of attributes subsequently falls below \p min_dense, the attributes are returned to compact storage. If \p max_compact is set to 0 (zero), dense storage always used. \p plist_id is an object creation property list (\p ocpl), as it can be a dataset or group creation property list identifier.

The function will return a negative value if the filter number is out of range. The structure of the \p flags argument is discussed in H5Pset_filter(). On input, \p cd_nelmts indicates the number of entries in the \p cd_values array, as allocated by the caller; on return, \p cd_nelmts contains the number of values defined by the filter. If \p name is a pointer to an array of at least \p namelen bytes, the filter name will be copied into that array. The name will be null terminated if \p namelen is large enough. The filter name returned will be the name appearing in the file, the name registered for the filter, or an empty string. \p filter_config is the bit field described in H5Zget_filter_info().

Returns:

\herr_t \details H5Pget_filter_by_id2() returns information about the filter specified in \p filter_id, a filter identifier. \p plist_id must be a dataset or group creation property list and \p filter_id must be in the associated filter pipeline. The \p filter_id and \p flags parameters are used in the same manner as described in the discussion of H5Pset_filter(). Aside from the fact that they are used for output, the parameters \p cd_nelmts and \p cd_values[] are used in the same manner as described in the discussion of H5Pset_filter(). On input, the \p cd_nelmts parameter indicates the number of entries in the \p cd_values[] array allocated by the calling program; on exit it contains the number of values defined by the filter. On input, the \p namelen parameter indicates the number of characters allocated for the filter name by the calling program in the array \p name[]. On exit \p name[] contains the name of the filter with one character of the name in each element of the array. \p filter_config is the bit field described in H5Zget_filter_info(). If the filter specified in \p filter_id is not set for the property list, an error will be returned and H5Pget_filter_by_id2() will fail.

\ingroup OCPL \brief Sets tracking and indexing of attribute creation order \plist_id

Parameters:

crt_order_flags - [in] Flags specifying whether to track and index attribute creation order. \em Default: No flag set; attribute creation order is neither tracked not indexed

Returns:

\herr_t \details H5Pset_attr_creation_order() sets flags for tracking and indexing attribute creation order on an object. \p plist_id is a dataset or group creation property list identifier. \p crt_order_flags contains flags with the following meanings:

#H5P_CRT_ORDER_TRACKED	Attribute creation order is tracked but not necessarily indexed.
#H5P_CRT_ORDER_INDEXED	Attribute creation order is indexed (requires #H5P_CRT_ORDER_TRACKED).

Default behavior is that attribute creation order is neither tracked nor indexed. H5Pset_attr_creation_order() can be used to set attribute creation order tracking, or to set attribute creation order tracking and indexing. \note If a creation order index is to be built, it must be specified in the object creation property list. HDF5 currently provides no mechanism to turn on attribute creation order tracking at object creation time and to build the index later.

Parameters:

max_compact - [in] Maximum number of attributes to be stored in compact storage (\em Default: 8); must be greater than or equal to \p min_dense

min_dense - [in] Minimum number of attributes to be stored in dense storage (\em Default: 6)

Returns:

\herr_t \details H5Pset_attr_phase_change() sets threshold values for attribute storage on an object. These thresholds determine the point at which attribute storage changes from compact storage (i.e., storage in the object header) to dense storage (i.e., storage in a heap and indexed with a B-tree). In the general case, attributes are initially kept in compact storage. When the number of attributes exceeds \p max_compact, attribute storage switches to dense storage. If the number of attributes subsequently falls below \p min_dense, the attributes are returned to compact storage. If \p max_compact is set to 0 (zero), dense storage is always used. \p min_dense must be set to 0 (zero) when \p max_compact is 0 (zero). \p plist_id is a dataset or group creation property list identifier.

Parameters:

Returns:

\herr_t \par_compr_note \details H5Pset_deflate() sets the deflate compression method and the compression level, \p level, for a dataset or group creation property list, \p plist_id. The filter identifier set in the property list is #H5Z_FILTER_DEFLATE. The compression level, \p level, is a value from zero to nine, inclusive. A compression level of 0 (zero) indicates no compression; compression improves but speed slows progressively from levels 1 through 9:

Compression Level	Gzip Action
0	No compression
1	Best compression speed; least compression
2 through 8	Compression improves; speed degrades
9	Best compression ratio; slowest speed

Note that setting the compression level to 0 (zero) does not turn off use of the gzip filter; it simply sets the filter to perform no compression as it processes the data. HDF5 relies on GNU gzip for this compression.

\ingroup OCPL \brief Adds a filter to the filter pipeline \ocpl_id{plist_id}

Parameters:

filter - [in] Filter identifier for the filter to be added to the pipeline

flags - [in] Bit vector specifying certain general properties of the filter

cd_nelmts - [in] Number of elements in \p c_values

c_values - [in] Auxiliary data for the filter

Returns:

\herr_t \details H5Pset_filter() adds the specified \p filter identifier and corresponding properties to the end of an output filter pipeline. \p plist_id must be either a dataset creation property list or group creation property list identifier. If \p plist_id is a dataset creation property list identifier, the filter is added to the raw data filter pipeline. If \p plist_id is a group creation property list identifier, the filter is added to the link filter pipeline, which filters the fractal heap used to store most of the link metadata in certain types of groups. The only predefined filters that can be set in a group creation property list are the gzip filter (#H5Z_FILTER_DEFLATE) and the Fletcher32 error detection filter (#H5Z_FILTER_FLETCHER32). The array \p cd_values contains \p cd_nelmts unsigned integers which are auxiliary data for the filter. The values are typically used as parameters to control the filter. In a filter's \p set_local method (called from \p H5Dcreate), the values are interpreted and possibly modified before they are used to control the filter. These, possibly modified values, are then stored in the dataset object header as auxiliary data for the filter. The \p flags argument is a bit vector with the following fields specifying certain general properties of the filter:

#H5Z_FLAG_OPTIONAL

If this bit is set then the filter is optional. If the filter fails (see below) during an H5Dwrite() operation then the filter is just excluded from the pipeline for the chunk for which it failed; the filter will not participate in the pipeline during an H5Dread() of the chunk. This is commonly used for compression filters: if the filter result would be larger than the input, then the compression filter returns failure and the uncompressed data is stored in the file. This flag should not be set for the Fletcher32 checksum filter as it will bypass the checksum filter without reporting checksum errors to an application.

#H5Z_FLAG_MANDATORY

If the filter is required, that is, set to mandatory, and the filter fails, the library’s behavior depends on whether the chunk cache is in use: \li If the chunk cache is enabled, data chunks will be flushed to the file during H5Dclose() and the library will return the failure in H5Dclose(). \li When the chunk cache is disabled or not big enough, or the chunk is being evicted from the cache, the failure will happen during H5Dwrite(). In each case, the library will still write to the file all data chunks that were processed by the filter before the failure occurred. For example, assume that an application creates a dataset of four chunks, the chunk cache is enabled and is big enough to hold all four chunks, and the filter fails when it tries to write the fourth chunk. The actual flush of the chunks will happen during H5Dclose(), not H5Dwrite(). By the time H5Dclose() fails, the first three chunks will have been written to the file. Even though H5Dclose() fails, all the resources will be released and the file can be closed properly. If, however, the filter fails on the second chunk, only the first chunk will be written to the file as nothing further can be written once the filter fails.

The \p filter parameter specifies the filter to be set. Valid pre-defined filter identifiers are as follows:

#H5Z_FILTER_DEFLATE	Data compression filter, employing the gzip algorithm
#H5Z_FILTER_SHUFFLE	Data shuffling filter
#H5Z_FILTER_FLETCHER32	Error detection filter, employing the Fletcher32 checksum algorithm
#H5Z_FILTER_SZIP	Data compression filter, employing the SZIP algorithm
#H5Z_FILTER_NBIT	Data compression filter, employing the N-Bit algorithm
#H5Z_FILTER_SCALEOFFSET	Data compression filter, employing the scale-offset algorithm

Also see H5Pset_edc_check() and H5Pset_filter_callback(). \note When a non-empty filter pipeline is used with a group creation property list, the group will be created with the new group file format. The filters will come into play only when dense storage is used (see H5Pset_link_phase_change()) and will be applied to the group’s fractal heap. The fractal heap will contain most of the group’s link metadata, including link names. \note When working with group creation property lists, if you are adding a filter that is not in HDF5’s set of predefined filters, i.e., a user-defined or third-party filter, you must first determine that the filter will work for a group. See the discussion of the set local and can apply callback functions in H5Zregister(). \note If multiple filters are set for a property list, they will be applied to each chunk of raw data for datasets or each block of the fractal heap for groups in the order in which they were set. \note Filters can be applied only to chunked datasets; they cannot be used with other dataset storage methods, such as contiguous, compact, or external datasets. \note Dataset elements of variable-length and dataset region reference datatypes are stored in separate structures in the file called heaps. Filters cannot currently be applied to these heaps. \note Filter Behavior in HDF5:
Filters can be inserted into the HDF5 pipeline to perform functions such as compression and conversion. As such, they are a very flexible aspect of HDF5; for example, a user-defined filter could provide encryption for an HDF5 dataset. \note A filter can be declared as either required or optional. Required is the default status; optional status must be explicitly declared. \note A required filter that fails or is not defined causes an entire output operation to fail; if it was applied when the data was written, such a filter will cause an input operation to fail. \note The following table summarizes required filter behavior.

	Required FILTER_X not available	FILTER_X available
H5Pset_	Will fail.	Will succeed.
H5Dwrite with FILTER_X set	Will fail.	Will succeed; FILTER_X will be applied to the data.
H5Dread with FILTER_X set	Will fail.	Will succeed.

\note An optional filter can be set for an HDF5 dataset even when the filter is not available. Such a filter can then be applied to the dataset when it becomes available on the original system or when the file containing the dataset is processed on a system on which it is available. \note A filter can be declared as optional through the use of the #H5Z_FLAG_OPTIONAL flag with H5Pset_filter(). \note Consider a situation where one is creating files that will normally be used only on systems where the optional (and fictional) filter FILTER_Z is routinely available. One can create those files on system A, which lacks FILTER_Z, create chunked datasets in the files with FILTER_Z defined in the dataset creation property list, and even write data to those datasets. The dataset object header will indicate that FILTER_Z has been associated with this dataset. But since system A does not have FILTER_Z, dataset chunks will be written without it being applied. \note HDF5 has a mechanism for determining whether chunks are actually written with the filters specified in the object header, so while the filter remains unavailable, system A will be able to read the data. Once the file is moved to system B, where FILTER_Z is available, HDF5 will apply FILTER_Z to any data rewritten or new data written in these datasets. Dataset chunks that have been written on system B will then be unreadable on system A; chunks that have not been re-written since being written on system A will remain readable on system A. All chunks will be readable on system B. \note The following table summarizes optional filter behavior.

	FILTER_Z not available	FILTER_Z available with encode and decode	FILTER_Z available decode only
H5Pset_	Will succeed.	Will succeed.	Will succeed.
H5Dread with FILTER_Z set	Will succeed if FILTER_Z has not actually been applied to data.	Will succeed.	Will succeed.
H5Dwrite with FILTER_Z set	Will succeed; FILTER_Z will not be applied to the data.	Will succeed; FILTER_Z will be applied to the data.	Will succeed; FILTER_Z will not be applied to the data.

\note The above principles apply generally in the use of HDF5 optional filters insofar as HDF5 does as much as possible to complete an operation when an optional filter is unavailable. (The SZIP filter is an exception to this rule; see H5Pset_szip() for details.)

In the original implementation, however, the checksum value was calculated incorrectly on little-endian systems. The error was fixed in HDF5 Release 1.6.3. \attention As a result of this fix, an HDF5 library of Release 1.6.0 through Release 1.6.2 cannot read a dataset created or written with Release 1.6.3 or later if the dataset was created with the checksum filter and the filter is enabled in the reading library. (Libraries of Release 1.6.3 and later understand the earlier error and compensate appropriately.) \attention \b Work-around: An HDF5 library of Release 1.6.2 or earlier will be able to read a dataset created or written with the checksum filter by an HDF5 library of Release 1.6.3 or later if the checksum filter is disabled for the read operation. This can be accomplished via a call to H5Pset_edc_check() with the value #H5Z_DISABLE_EDC in the second parameter. This has the obvious drawback that the application will be unable to verify the checksum, but the data does remain accessible.

\ingroup FCPL \brief Retrieves shared object header message phase change information \fcpl_id{plist_id}

Parameters:

max_list - [out] Threshold above which storage of a shared object header message index shifts from list to B-tree

min_btree - [out] Threshold below which storage of a shared object header message index reverts to list format

Returns:

\herr_t \details H5Pget_shared_mesg_phase_change() retrieves the threshold values for storage of shared object header message indexes in a file. These phase change thresholds determine the point at which the index storage mechanism changes from a more compact list format to a more performance-oriented B-tree format, and vice-versa. By default, a shared object header message index is initially stored as a compact list. When the number of messages in an index exceeds the specified \p max_list threshold, storage switches to a B-tree format for improved performance. If the number of messages subsequently falls below the \p min_btree threshold, the index will revert to the list format. If \p max_list is set to 0 (zero), shared object header message indexes in the file will always be stored as B-trees. \p plist_id specifies the file creation property list.

\ingroup FCPL \brief Sets shared object header message storage phase change thresholds \fcpl_id{plist_id}

Parameters:

max_list - [in] Threshold above which storage of a shared object header message index shifts from list to B-tree

min_btree - [in] Threshold below which storage of a shared object header message index reverts to list format

Returns:

\herr_t \details H5Pset_shared_mesg_phase_change() sets threshold values for storage of shared object header message indexes in a file. These phase change thresholds determine the point at which the index storage mechanism changes from a more compact list format to a more performance-oriented B-tree format, and vice-versa. By default, a shared object header message index is initially stored as a compact list. When the number of messages in an index exceeds the threshold value of \p max_list, storage switches to a B-tree for improved performance. If the number of messages subsequently falls below the \p min_btree threshold, the index will revert to the list format. If \p max_list is set to 0 (zero), shared object header message indexes in the file will be created as B-trees and will never revert to lists. \p plist_id specifies the file creation property list.

\ingroup FCPL \brief \fcpl_id{plist_id}

Parameters:

ik - [in] Symbol table tree rank

lk - [in] Symbol table node size

Returns:

\herr_t \details H5Pset_sym_k() sets the size of parameters used to control the symbol table nodes. This function is valid only for file creation property lists. Passing in a value of zero (0) for one of the parameters retains the current value. \p ik is one half the rank of a B-tree that stores a symbol table for a group. Internal nodes of the symbol table are on average 75% full. That is, the average rank of the tree is 1.5 times the value of \p ik. The HDF5 library uses (\p ik*2) as the maximum # of entries before splitting a B-tree node. Since only 2 bytes are used in storing # of entries for a B-tree node in an HDF5 file, (\p ik*2) cannot exceed 65536. The default value for \p ik is 16. \p lk is one half of the number of symbols that can be stored in a symbol table node. A symbol table node is the leaf of a symbol table tree which is used to store a group. When symbols are inserted randomly into a group, the group's symbol table nodes are 75% full on average. That is, they contain 1.5 times the number of symbols specified by \p lk. The default value for \p lk is 4.

Returns:

\herr_t \details H5Pget_core_write_tracking() retrieves information about the write tracking feature used by the core VFD. When a file is created or opened for writing using the core virtual file driver (VFD) with the backing store option turned on, the VFD can be configured to track changes to the file and only write out the modified bytes. To avoid a large number of small writes, the changes can be aggregated into pages of a user-specified size. The core VFD is also known as the memory VFD. The driver identifier is #H5FD_CORE. \note This function is only for use with the core VFD and must be used after the call to H5Pset_fapl_core(). It is an error to use this function with any other VFD. \note This function only applies to the backing store write operation, which typically occurs when the file is flushed or closed. This function has no relationship to the increment parameter passed to H5Pset_fapl_core(). \note For optimum performance, the \p page_size parameter should be a power of two.

Driver Name	Driver Identifier	Description	Related Function
POSIX	#H5FD_SEC2	This driver uses POSIX file-system functions like read and write to perform I/O to a single, permanent file on local disk with no system buffering. This driver is POSIX-compliant and is the default file driver for all systems.	H5Pset_fapl_sec2()
Direct	#H5FD_DIRECT	This is the #H5FD_SEC2 driver, except data is written to or read from the file synchronously without being cached by the system.	H5Pset_fapl_direct()
Log	#H5FD_LOG	This is the #H5FD_SEC2 driver with logging capabilities.	H5Pset_fapl_log()
Windows	#H5FD_WINDOWS	This driver was modified in HDF5-1.8.8 to be a wrapper of the POSIX driver, #H5FD_SEC2. This change should not affect user applications.	H5Pset_fapl_windows()
STDIO	#H5FD_STDIO	This driver uses functions from the standard C stdio.h to perform I/O to a single, permanent file on local disk with additional system buffering.	H5Pset_fapl_stdio()
Memory	#H5FD_CORE	With this driver, an application can work with a file in memory for faster reads and writes. File contents are kept in memory until the file is closed. At closing, the memory version of the file can be written back to disk or abandoned.	H5Pset_fapl_core()
Family	#H5FD_FAMILY	With this driver, the HDF5 file’s address space is partitioned into pieces and sent to separate storage files using an underlying driver of the user’s choice. This driver is for systems that do not support files larger than 2 gigabytes.	H5Pset_fapl_family()
Multi	#H5FD_MULTI	With this driver, data can be stored in multiple files according to the type of data. I/O might work better if data is stored in separate files based on the type of data. The Split driver is a special case of this driver.	H5Pset_fapl_multi()
Parallel	#H5FD_MPIO	This is the standard HDF5 file driver for parallel file systems. This driver uses the MPI standard for both communication and file I/O.	H5Pset_fapl_mpio()
Parallel POSIX	H5FD_MPIPOSIX	This driver is no longer available.
Stream	H5FD_STREAM	This driver is no longer available.

For example, the struct used for the MULTI driver is \c H5FD_multi_fapl_t defined in H5FDmulti.c. If no driver-specific properties have been registered, H5Pget_driver_info() returns NULL. \note H5Pget_driver_info() and H5Pset_driver() are used only when creating a virtual file driver (VFD) in the virtual file layer (VFL).

\ingroup FAPL \brief Retrieves the file access property list setting that determines whether an HDF5 object will be evicted from the library's metadata cache when it is closed \fapl_id

Parameters:

evict_on_close - [out] Pointer to a variable that will indicate if the object will be evicted on close

Returns:

\herr_t \details The library's metadata cache is fairly conservative about holding on to HDF5 object metadata (object headers, chunk index structures, etc.), which can cause the cache size to grow, resulting in memory pressure on an application or system. When enabled, the "evict on close" property will cause all metadata for an object to be immediately evicted from the cache as long as it is not referenced by any other open object. See H5Pset_evict_on_close() for additional notes on behavior.

\ingroup FAPL \brief Retrieves a copy of the file image designated as the initial content and structure of a file \fapl_id

Parameters:

buf_ptr_ptr - [in,out] On input, \c NULL or a pointer to a pointer to a buffer that contains the file image.\n On successful return, if \p buf_ptr_ptr is not \c NULL, \Code{*buf_ptr_ptr} will contain a pointer to a copy of the initial image provided in the last call to H5Pset_file_image() for the supplied \p fapl_id. If no initial image has been set, \Code{*buf_ptr_ptr} will be \c NULL.

buf_len_ptr - [in,out] On input, \c NULL or a pointer to a buffer specifying the required size of the buffer to hold the file image.\n On successful return, if \p buf_len_ptr was not passed in as \c NULL, \p buf_len_ptr will return the required size in bytes of the buffer to hold the initial file image in the supplied file access property list, \p fapl_id. If no initial image is set, the value of \Code{*buf_len_ptr} will be set to 0 (zero)

Returns:

\herr_t \details H5Pget_file_image() allows an application to retrieve a copy of the file image designated for a VFD to use as the initial contents of a file. If file image callbacks are defined, H5Pget_file_image() will use them when allocating and loading the buffer to return to the application (see H5Pset_file_image_callbacks()). If file image callbacks are not defined, the function will use \c malloc and \c memcpy. When \c malloc and \c memcpy are used, it is the caller’s responsibility to discard the returned buffer with a call to \c free. It is the responsibility of the calling application to free the buffer whose address is returned in \p buf_ptr_ptr. This can be accomplished with \c free if file image callbacks have not been set (see H5Pset_file_image_callbacks()) or with the appropriate method if file image callbacks have been set.

Returns:

\herr_t \note The \c in direction applies only to the \ref H5AC_cache_config_t.version field. All other fields are \c out parameters. \details The fields of the #H5AC_cache_config_t structure are shown below: \snippet H5ACpublic.h H5AC_cache_config_t_snip \click4more H5Pget_mdc_config() gets the initial metadata cache configuration contained in a file access property list and loads it into the instance of #H5AC_cache_config_t pointed to by the \p config_ptr parameter. This configuration is used when the file is opened. Note that the version field of \Code{*config_ptr} must be initialized; this allows the library to support earlier versions of the #H5AC_cache_config_t structure. See the overview of the metadata cache in the special topics section of the user guide for details on the configuration data returned. If you haven't read and understood that documentation, the results of this call will not make much sense.

\ingroup FAPL \brief Gets metadata cache logging options \fapl_id{plist_id}

Parameters:

is_enabled - [out] Flag whether logging is enabled

location - [out] Location of log in UTF-8/ASCII (file path/name) (On Windows, this must be ASCII)

location_size - [out] Size in bytes of the location string

start_on_access - [out] Whether the logging begins as soon as the file is opened or created

Returns:

\herr_t \details The metadata cache is a central part of the HDF5 library through which all file metadata reads and writes take place. File metadata is normally invisible to the user and is used by the library for purposes such as locating and indexing data. File metadata should not be confused with user metadata, which consists of attributes created by users and attached to HDF5 objects such as datasets via \ref H5A API calls. Due to the complexity of the cache, a trace/logging feature has been created that can be used by HDF5 developers for debugging and performance analysis. The functions that control this functionality will normally be of use to a very limited number of developers outside of The HDF Group. The functions have been documented to help users create logs that can be sent with bug reports. Control of the log functionality is straightforward. Logging is enabled via the H5Pset_mdc_log_options() function, which will modify the file access property list used to open or create a file. This function has a flag that determines whether logging begins at file open or starts in a paused state. Log messages can then be controlled via the H5Fstart_mdc_logging() / H5Fstop_mdc_logging() functions. H5Pget_mdc_log_options() can be used to examine a file access property list, and H5Fget_mdc_logging_status() will return the current state of the logging flags. The log format is described in the Metadata Cache Logging document.

Returns:

\herr_t \details H5Pget_metadata_read_attempts() retrieves the number of read attempts that is set in the file access property list \p plist_id. For a default file access property list, the value retrieved will depend on whether the user sets the number of attempts via H5Pset_metadata_read_attempts():

• If the number of attempts is set to N, the value returned will be N.
• If the number of attempts is not set, the value returned will be the default for non-SWMR access (1). SWMR is short for single-writer/multiple-reader.

For the file access property list of a specified HDF5 file, the value retrieved will depend on how the file is opened and whether the user sets the number of read attempts via H5Pset_metadata_read_attempts():

• For a file opened with SWMR access:
  • If the number of attempts is set to N, the value returned will be N.
  • If the number of attempts is not set, the value returned will be the default for SWMR access (100).
• For a file opened without SWMR access, the value retrieved will always be the default for non-SWMR access (1). The value set via H5Pset_metadata_read_attempts() does not have any effect on non-SWMR access.

\ingroup FAPL \brief Retrieves type of data property for MULTI driver

Parameters:

fapl_id - [in] File access property list or data transfer property list identifier

type - [out] Type of data

Returns:

\herr_t \details H5Pget_multi_type() retrieves the type of data setting from the file access or data transfer property list \p fapl_id. This enables a user application to specify the type of data the application wishes to access so that the application can retrieve a file handle for low-level access to the particular member of a set of MULTI files in which that type of data is stored. The file handle is retrieved with a separate call to H5Fget_vfd_handle() (or, in special circumstances, to H5FDget_vfd_handle(); see the Virtual File Layer documentation for more information. The type of data returned in \p type will be one of those listed in the discussion of the \p type parameter in the description of the function H5Pset_multi_type(). Use of this function is only appropriate for an HDF5 file written as a set of files with the MULTI file driver.

Parameters:

threshold - [in] Threshold value. Note that setting the threshold value to 0 (zero) has the effect of a special case, forcing everything to be aligned

alignment - [in] Alignment value

Returns:

\herr_t \details H5Pset_alignment() sets the alignment properties of a file access property list so that any file object greater than or equal in size to \p threshold bytes will be aligned on an address that is a multiple of \p alignment. The addresses are relative to the end of the user block; the alignment is calculated by subtracting the user block size from the absolute file address and then adjusting the address to be a multiple of \p alignment. Default values for \p threshold and \p alignment are one, implying no alignment. Generally the default values will result in the best performance for single-process access to the file. For MPI IO and other parallel systems, choose an alignment that is a multiple of the disk block size. If the file space handling strategy is set to #H5F_FSPACE_STRATEGY_PAGE, then the alignment set via this routine is ignored. The file space handling strategy is set by H5Pset_file_space_strategy().

Due to the hashing strategy, this value should ideally be a prime number. As a rule of thumb, this value should be at least 10 times the number of chunks that can fit in \p rdcc_nbytes bytes. For maximum performance, this value should be set approximately 100 times that number of chunks. The default value is 521.

rdcc_nbytes - [in] Total size of the raw data chunk cache in bytes. The default size is 1 MB per dataset.

rdcc_w - [in] 0 The chunk preemption policy for all datasets. This must be between 0 and 1 inclusive and indicates the weighting according to which chunks which have been fully read or written are penalized when determining which chunks to flush from cache. A value of 0 means fully read or written chunks are treated no differently than other chunks (the preemption is strictly LRU), while a value of 1 means fully read or written chunks are always preempted before other chunks. If your application only reads or writes data once, this can be safely set to 1. Otherwise, this should be set lower depending on how often you re-read or re-write the same data. The default value is 0.75. If the value passed is #H5D_CHUNK_CACHE_W0_DEFAULT, then the property will not be set on the dataset access property list, and the parameter will come from the file access property list.

Returns:

\herr_t \details H5Pset_cache() sets the number of elements, the total number of bytes, and the preemption policy value for all datasets in a file on the file’s file access property list. The raw data chunk cache inserts chunks into the cache by first computing a hash value using the address of a chunk and then by using that hash value as the chunk’s index into the table of cached chunks. In other words, the size of this hash table and the number of possible hash values are determined by the \p rdcc_nslots parameter. If a different chunk in the cache has the same hash value, a collision will occur, which will reduce efficiency. If inserting the chunk into the cache would cause the cache to be too big, then the cache will be pruned according to the \p rdcc_w0 parameter. The \p mdc_nelmts parameter is no longer used; any value passed in that parameter will be ignored. \b Motivation: Setting raw data chunk cache parameters can be done with H5Pset_cache(), H5Pset_chunk_cache(), or a combination of both. H5Pset_cache() is used to adjust the chunk cache parameters for all datasets via a global setting for the file, and H5Pset_chunk_cache() is used to adjust the chunk cache parameters for individual datasets. When both are used, parameters set with H5Pset_chunk_cache() will override any parameters set with H5Pset_cache(). \note Optimum chunk cache parameters may vary widely depending on different data layout and access patterns. For datasets with low performance requirements for example, changing the cache settings can save memory. \note Note: Raw dataset chunk caching is not currently supported when using the MPI I/O and MPI POSIX file drivers in read/write mode; see H5Pset_fapl_mpio(). When using this file driver, all calls to H5Dread() and H5Dwrite() will access the disk directly, and H5Pset_cache() will have no effect on performance. \note Raw dataset chunk caching is supported when these drivers are used in read-only mode.

This write tracking feature is enabled and disabled with \p is_enabled. The default setting is that write tracking is disabled, or off. To avoid a large number of small writes, changes can be aggregated into pages of a user-specified size, \p page_size. Setting \p page_size to 1 enables tracking with no page aggregation. The backing store option is set via the function H5Pset_fapl_core. \attention \parblock This function is only for use with the core VFD and must be used after the call to H5Pset_fapl_core().

This function only applies to the backing store write operation which typically occurs when the file is flushed or closed. This function has no relationship to the increment parameter passed to H5Pset_fapl_core(). For optimum performance, the \p page_size parameter should be a power of two.

\ingroup FAPL \brief Sets the number of files that can be held open in an external link open file cache \par Motivation \parblock The external link open file cache holds files open after they have been accessed via an external link. This cache reduces the number of times such files are opened when external links are accessed repeatedly and can significantly improves performance in certain heavy-use situations and when low-level file opens or closes are expensive. H5Pset_elink_file_cache_size() sets the number of files that will be held open in an external link open file cache. H5Pget_elink_file_cache_size() retrieves the size of an existing cache; and H5Fclear_elink_file_cache() clears an existing cache without closing it. \endparblock \fapl_id{plist_id}

Parameters:

efc_size - [in] External link open file cache size in number of files Default setting is 0 (zero).

Returns:

\herr_t \details H5Pset_elink_file_cache_size() specifies the number of files that will be held open in an external link open file cache. The default external link open file cache size is 0 (zero), meaning that files accessed via an external link are not held open. Setting the cache size to a positive integer turns on the cache; setting the size back to zero turns it off. With this property set, files are placed in the external link open file cache cache when they are opened via an external link. Files are then held open until either they are evicted from the cache or the parent file is closed. This property setting can improve performance when external links are repeatedly accessed. When the cache is full, files will be evicted using a least recently used (LRU) scheme; the file which has gone the longest time without being accessed through the parent file will be evicted and closed if nothing else is holding that file open. Files opened through external links inherit the parent file’s file access property list by default, and therefore inherit the parent file’s external link open file cache setting. When child files contain external links of their own, the caches can form a graph of cached external files. Closing the last external reference to such a graph will recursively close all files in the graph, even if cycles are present. \par Example \parblock The following code sets up an external link open file cache that will hold open up to 8 files reached through external links:

 status = H5Pset_elink_file_cache_size(fapl_id, 8);

Parameters:

evict_on_close - [in] Whether the HDF5 object should be evicted on close

Returns:

\herr_t \details The library's metadata cache is fairly conservative about holding on to HDF5 object metadata(object headers, chunk index structures, etc.), which can cause the cache size to grow, resulting in memory pressure on an application or system. When enabled, the "evict on close" property will cause all metadata for an object to be evicted from the cache as long as metadata is not referenced by any other open object. This function only applies to file access property lists. The default library behavior is to not evict on object or file close. When applied to a file access property list, any subsequently opened object will inherit the "evict on close" property and will have its metadata evicted when the object is closed.

\herr_t \details H5Pset_family_offset() sets the offset property in the file access property list \p fapl_id so that the user application can retrieve a file handle for low-level access to a particular member of a family of files. The file handle is retrieved with a separate call to H5Fget_vfd_handle() (or, in special circumstances, to H5FDget_vfd_handle(); see \ref VFL). The value of \p offset is an offset in bytes from the beginning of the HDF5 file, identifying a user-determined location within the HDF5 file. The file handle the user application is seeking is for the specific member-file in the associated family of files to which this offset is mapped.

Returns:

\herr_t \details H5Pset_fclose_degree() sets the file close degree property \p degree in the file access property list \p fapl_id. The value of \p degree determines how aggressively H5Fclose() deals with objects within a file that remain open when H5Fclose() is called to close that file. \p degree can have any one of four valid values:

Degree name	H5Fclose behavior with no open object in file	H5Fclose behavior with open object(s) in file
#H5F_CLOSE_WEAK	Actual file is closed.	Access to file identifier is terminated; actual file close is delayed until all objects in file are closed
#H5F_CLOSE_SEMI	Actual file is closed.	Function returns FAILURE
#H5F_CLOSE_STRONG	Actual file is closed.	All open objects remaining in the file are closed then file is closed
#H5F_CLOSE_DEFAULT	The VFL driver chooses the behavior. Currently, all VFL drivers set this value to #H5F_CLOSE_WEAK, except for the MPI-I/O driver, which sets it to #H5F_CLOSE_SEMI.

\warning If a file is opened multiple times without being closed, each open operation must use the same file close degree setting. For example, if a file is already open with #H5F_CLOSE_WEAK, an H5Fopen() call with #H5F_CLOSE_STRONG will fail.

H5Pset_file_image_callbacks() allows an application to control the management of file image buffers through user defined callbacks. These callbacks can be used in the management of file image buffers in property lists and with certain file drivers. H5Pset_file_image_callbacks() must be used before any file image has been set in the file access property list. Once a file image has been set, the function will fail. The callback routines set up by H5Pset_file_image_callbacks() are invoked when a new file image buffer is allocated, when an existing file image buffer is copied or resized, or when a file image buffer is released from use. Some file drivers allow the use of user-defined callback functions for allocating, freeing, and copying the driver’s internal buffer, potentially allowing optimizations such as avoiding large \c malloc and \c memcpy operations, or to perform detailed logging. From the perspective of the HDF5 library, the operations of the \ref H5FD_file_image_callbacks_t.image_malloc "image_malloc", \ref H5FD_file_image_callbacks_t.image_memcpy "image_memcpy", \ref H5FD_file_image_callbacks_t.image_realloc "image_realloc", and \ref H5FD_file_image_callbacks_t.image_free "image_free" callbacks must be identical to those of the corresponding C standard library calls (\c malloc, \c memcpy, \c realloc, and \c free). While the operations must be identical, the file image callbacks have more parameters. The return values of \ref H5FD_file_image_callbacks_t.image_malloc "image_malloc" and \ref H5FD_file_image_callbacks_t.image_realloc "image_realloc" are identical to the return values of \c malloc and \c realloc. The return values of \ref H5FD_file_image_callbacks_t.image_malloc "image_malloc" and \ref H5FD_file_image_callbacks_t.image_free "image_free" differ from the return values of \c memcpy and \c free in that the return values of \ref H5FD_file_image_callbacks_t.image_memcpy "image_memcpy" and \ref H5FD_file_image_callbacks_t.image_free "image_free" can also indicate failure. The callbacks and their parameters, along with a struct and an \c ENUM required for their use, are described below. Callback struct and \c ENUM: The callback functions set up by H5Pset_file_image_callbacks() use a struct and an \c ENUM that are defined as follows The struct #H5FD_file_image_callbacks_t serves as a container for the callback functions and a pointer to user-supplied data. The struct is defined as follows: \snippet H5FDpublic.h H5FD_file_image_callbacks_t_snip Elements of the #H5FD_file_image_op_t are used by the callbacks to invoke certain operations on file images. The ENUM is defined as follows: \snippet H5FDpublic.h H5FD_file_image_op_t_snip The elements of the #H5FD_file_image_op_t are used in the following callbacks: - The \ref H5FD_file_image_callbacks_t.image_malloc "image_malloc" callback contains a pointer to a function that must appear to HDF5 to have functionality identical to that of the standard C library \c malloc() call. - Signature in #H5FD_file_image_callbacks_t: \snippet H5FDpublic.h image_malloc_snip \n - The \ref H5FD_file_image_callbacks_t.image_memcpy "image_memcpy" callback contains a pointer to a function that must appear to HDF5 to have functionality identical to that of the standard C library \c memcopy() call, except that it returns a \p NULL on failure. (The \c memcpy C Library routine is defined to return the \p dest parameter in all cases.) - Setting \ref H5FD_file_image_callbacks_t.image_memcpy "image_memcpy" to \c NULL indicates that HDF5 should invoke the standard C library \c memcpy() routine when copying buffers. - Signature in #H5FD_file_image_callbacks_t: \snippet H5FDpublic.h image_memcpy_snip \n - The \ref H5FD_file_image_callbacks_t.image_realloc "image_realloc" callback contains a pointer to a function that must appear to HDF5 to have functionality identical to that of the standard C library \c realloc() call. - Setting \ref H5FD_file_image_callbacks_t.image_realloc "image_realloc" to \p NULL indicates that HDF5 should invoke the standard C library \c realloc() routine when resizing file image buffers. - Signature in #H5FD_file_image_callbacks_t: \snippet H5FDpublic.h image_realloc_snip \n - The \ref H5FD_file_image_callbacks_t.image_free "image_free" callback contains a pointer to a function that must appear to HDF5 to have functionality identical to that of the standard C library \c free() call, except that it will return \c 0 (\c SUCCEED) on success and \c -1 (\c FAIL) on failure. - Setting \ref H5FD_file_image_callbacks_t.image_free "image_free" to \c NULL indicates that HDF5 should invoke the standard C library \c free() routine when releasing file image buffers. - Signature in #H5FD_file_image_callbacks_t: \snippet H5FDpublic.h image_free_snip \n - The \ref H5FD_file_image_callbacks_t.udata_copy "udata_copy" callback contains a pointer to a function that, from the perspective of HDF5, allocates a buffer of suitable size, copies the contents of the supplied \p udata into the new buffer, and returns the address of the new buffer. The function returns NULL on failure. This function is necessary if a non-NULL \p udata parameter is supplied, so that property lists containing the image callbacks can be copied. If the \p udata parameter below is \c NULL, then this parameter should be \c NULL as well. - Signature in #H5FD_file_image_callbacks_t: \snippet H5FDpublic.h udata_copy_snip \n - The \ref H5FD_file_image_callbacks_t.udata_free "udata_free" callback contains a pointer to a function that, from the perspective of HDF5, frees a user data block. This function is necessary if a non-NULL udata parameter is supplied so that property lists containing image callbacks can be discarded without a memory leak. If the udata parameter below is \c NULL, this parameter should be \c NULL as well. - Signature in #H5FD_file_image_callbacks_t: \snippet H5FDpublic.h udata_free_snip - \p **udata**, the final field in the #H5FD_file_image_callbacks_t struct, provides a pointer to user-defined data. This pointer will be passed to the \ref H5FD_file_image_callbacks_t.image_malloc "image_malloc", \ref H5FD_file_image_callbacks_t.image_memcpy "image_memcpy", \ref H5FD_file_image_callbacks_t.image_realloc "image_realloc", and \ref H5FD_file_image_callbacks_t.image_free "image_free" callbacks. Define udata as \c NULL if no user-defined data is provided.

Returns:

\herr_t \details H5Pset_gc_references() sets the flag for garbage collecting references for the file. Dataset region references and other reference types use space in an HDF5 file's global heap. If garbage collection is on and the user passes in an uninitialized value in a reference structure, the heap might get corrupted. When garbage collection is off, however, and the user re-uses a reference, the previous heap block will be orphaned and not returned to the free heap space. When garbage collection is on, the user must initialize the reference structures to 0 or risk heap corruption. The default value for garbage collecting references is off.

\ingroup FAPL \brief Controls the range of library release versions used when creating objects in a file \fapl_id{plist_id}

Parameters:

low - [in] The earliest version of the library that will be used for writing objects

high - [in] The latest version of the library that will be used for writing objects

Returns:

\herr_t \details H5Pset_libver_bounds() controls the range of library release versions that will be used when creating objects in a file. The object format versions are determined indirectly from the library release versions specified in the call. This property is set in the file access property list specified by the parameter \p fapl_id. The parameter \p low sets the earliest possible format versions that the library will use when creating objects in the file. Note that earliest possible is different from earliest, as some features introduced in library versions later than 1.0.0 resulted in updates to object formats. The parameter \p high sets the latest format versions that the library will be allowed to use when creating objects in the file. The parameters \p low and \p high must be one of the enumerated values in the #H5F_libver_t struct, which is defined in H5Fpublic.h. The macro #H5F_LIBVER_LATEST is aliased to the highest enumerated value in #H5F_libver_t, indicating that this is currently the latest format available. The library supports the following five pairs of (\p low, \p high) combinations as derived from the values in #H5F_libver_t:

Value of \p low and \p high	Result
\p low=#H5F_LIBVER_EARLIEST \p high=#H5F_LIBVER_V18	\li The library will create objects with the earliest possible format versions. \li The library will allow objects to be created with the latest format versions available to library release 1.8.x. \li API calls that create objects or features that are available to versions of the library greater than 1.8.x release will fail.
\p low=#H5F_LIBVER_EARLIEST \p high=#H5F_LIBVER_V110	\li The library will create objects with the earliest possible format versions. \li The library will allow objects to be created with the latest format versions available to library release 1.10.x. Since 1.10.x is also #H5F_LIBVER_LATEST, there is no upper limit on the format versions to use. For example, if a newer format version is required to support a feature e.g. virtual dataset, this setting will allow the object to be created. \li This is the library default setting and provides the greatest format compatibility.
\p low=#H5F_LIBVER_V18 \p high=#H5F_LIBVER_V18	\li The library will create objects with the latest format versions available to library release 1.8.x. \li API calls that create objects or features that are available to versions of the library greater than 1.8.x release will fail. \li Earlier versions of the library may not be able to access objects created with this setting.
\p low=#H5F_LIBVER_V18 \p high=#H5F_LIBVER_V110	\li The library will create objects with the latest format versions available to library release 1.8.x. \li The library will allow objects to be created with the latest format versions available to library release 1.10.x. Since 1.10.x is also #H5F_LIBVER_LATEST, there is no upper limit on the format versions to use. For example, if a newer format version is required to support a feature e.g. virtual dataset, this setting will allow the object to be created. \li Earlier versions of the library may not be able to access objects created with this setting.

start_on_access - [in] Whether the logging will begin as soon as the file is opened or created

Returns:

\herr_t \details The metadata cache is a central part of the HDF5 library through which all file metadata reads and writes take place. File metadata is normally invisible to the user and is used by the library for purposes such as locating and indexing data. File metadata should not be confused with user metadata, which consists of attributes created by users and attached to HDF5 objects such as datasets via H5A API calls. Due to the complexity of the cache, a trace/logging feature has been created that can be used by HDF5 developers for debugging and performance analysis. The functions that control this functionality will normally be of use to a very limited number of developers outside of The HDF Group. The functions have been documented to help users create logs that can be sent with bug reports. Control of the log functionality is straightforward. Logging is enabled via the H5Pset_mdc_log_options() function, which will modify the file access property list used to open or create a file. This function has a flag that determines whether logging begins at file open or starts in a paused state. Log messages can then be controlled via the H5Fstart_mdc_logging() and H5Fstop_mdc_logging() function. H5Pget_mdc_log_options() can be used to examine a file access property list, and H5Fget_mdc_logging_status() will return the current state of the logging flags. The log format is described in [Metadata Cache Logging] (https://portal.hdfgroup.org/display/HDF5/Fine-tuning+the+Metadata+Cache).

Parameters:

Returns:

\herr_t \details H5Pset_meta_block_size() sets the minimum size, in bytes, of metadata block allocations when #H5FD_FEAT_AGGREGATE_METADATA is set by a VFL driver.

Each raw metadata block is initially allocated to be of the given size. Specific metadata objects (e.g., object headers, local heaps, B-trees) are then sub-allocated from this block. The default setting is 2048 bytes, meaning that the library will attempt to aggregate metadata in at least 2K blocks in the file. Setting the value to zero (\Code{0}) with this function will turn off metadata aggregation, even if the VFL driver attempts to use the metadata aggregation strategy. Metadata aggregation reduces the number of small data objects in the file that would otherwise be required for metadata. The aggregated block of metadata is usually written in a single write action and always in a contiguous block, potentially significantly improving library and application performance.

\ingroup FAPL \brief Sets the maximum size of the data sieve buffer \fapl_id{fapl_id}

Parameters:

size - [in] Maximum size, in bytes, of data sieve buffer

Returns:

\herr_t \details H5Pset_sieve_buf_size() sets \p size, the maximum size in bytes of the data sieve buffer, which is used by file drivers that are capable of using data sieving. The data sieve buffer is used when performing I/O on datasets in the file. Using a buffer which is large enough to hold several pieces of the dataset being read in for hyperslab selections boosts performance by quite a bit. The default value is set to 64KB, indicating that file I/O for raw data reads and writes will occur in at least 64KB blocks. Setting the value to zero (\Code{0}) with this API function will turn off the data sieving, even if the VFL driver attempts to use that strategy. Internally, the library checks the storage sizes of the datasets in the file. It picks the smaller one between the size from the file access property and the size of the dataset to allocate the sieve buffer for the dataset in order to save memory usage.

\ingroup FAPL \brief Sets the size of a contiguous block reserved for small data \fapl_id{fapl_id}

Parameters:

size - [in] Maximum size, in bytes, of the small data block. The default size is \Code{2048}.

Returns:

\herr_t \details H5Pset_small_data_block_size() reserves blocks of \p size bytes for the contiguous storage of the raw data portion of \Emph{small} datasets. The HDF5 library then writes the raw data from small datasets to this reserved space, thus reducing unnecessary discontinuities within blocks of meta data and improving I/O performance. A small data block is actually allocated the first time a qualifying small dataset is written to the file. Space for the raw data portion of this small dataset is suballocated within the small data block. The raw data from each subsequent small dataset is also written to the small data block until it is filled; additional small data blocks are allocated as required. The HDF5 library employs an algorithm that determines whether I/O performance is likely to benefit from the use of this mechanism with each dataset as storage space is allocated in the file. A larger \p size will result in this mechanism being employed with larger datasets. The small data block size is set as an allocation property in the file access property list identified by \p fapl_id. Setting \p size to zero (\Code{0}) disables the small data block mechanism.

\ingroup FAPL \brief Sets the metadata cache image option for a file access property list \fapl_id{plist_id}

Returns:

\herr_t \details H5Pset_mdc_image_config() sets the metadata cache image option with configuration values specified by \p config_ptr for the file access property list specified in \p plist_id. #H5AC_cache_image_config_t is defined as follows: \snippet H5ACpublic.h H5AC_cache_image_config_t_snip \click4more \par Limitations: While it is an obvious error to request a cache image when opening the file read only, it is not in general possible to test for this error in the H5Pset_mdc_image_config() call. Rather than fail the subsequent file open, the library silently ignores the file image request in this case.\n It is also an error to request a cache image on a file that does not support superblock extension messages (i.e. a superblock version less than 2). As above, it is not always possible to detect this error in the H5Pset_mdc_image_config() call, and thus the request for a cache image will fail silently in this case as well.\n Creation of cache images is currently disabled in parallel -- as above, any request for a cache image in this context will fail silently.\n Files with cache images may be read in parallel applications, but note that the load of the cache image is a collective operation triggered by the first operation that accesses metadata after file open (or, if persistent free space managers are enabled, on the first allocation or deallocation of file space, or read of file space manager status, whichever comes first). Thus the parallel process may deadlock if any process does not participate in this access.\n In long sequences of file closes and opens, infrequently accessed metadata can accumulate in the cache image to the point where the cost of storing and restoring this metadata exceeds the benefit of retaining frequently used metadata in the cache image. When implemented, the #H5AC_cache_image_config_t::entry_ageout should address this problem. In the interim, not requesting a cache image every n file close/open cycles may be an acceptable work around. The choice of \c n will be driven by application behavior, but \Code{n = 10} seems a good starting point.

Parameters:

min_meta_per - [in] Minimum metadata percentage to keep in the page buffer before allowing pages containing metadata to be evicted (Default is 0)

min_raw_per - [in] Minimum raw data percentage to keep in the page buffer before allowing pages containing raw data to be evicted (Default is 0)

Returns:

\herr_t \details H5Pset_page_buffer_size() sets buf_size, the maximum size in bytes of the page buffer. The default value is zero, meaning that page buffering is disabled. When a non-zero page buffer size is set, the library will enable page buffering if that size is larger or equal than a single page size if a paged file space strategy is enabled using the functions H5Pset_file_space_strategy() and H5Pset_file_space_page_size(). The page buffer layer captures all I/O requests before they are issued to the VFD and "caches" them in fixed sized pages. Once the total number of pages exceeds the page buffer size, the library evicts pages from the page buffer by writing them to the VFD. At file close, the page buffer is flushed writing all the pages to the file. If a non-zero page buffer size is set, and the file space strategy is not set to paged or the page size for the file space strategy is larger than the page buffer size, the subsequent call to H5Fcreate() or H5Fopen() using the \p plist_id will fail. The function also allows setting the minimum percentage of pages for metadata and raw data to prevent a certain type of data to evict hot data of the other type.

name_size - [in] Maximum length of \p name array

name - [out] Name of the external file

offset - [out] Pointer to a location to return an offset value

size - [out] Pointer to a location to return the size of the external file data

Returns:

\herr_t \details H5Pget_external() returns information about an external file. The external file is specified by its index, \p idx, which is a number from zero to N-1, where N is the value returned by H5Pget_external_count(). At most \p name_size characters are copied into the \p name array. If the external file name is longer than \p name_size with the null terminator, the return value is not null terminated (similar to strncpy()). If \p name_size is zero or \p name is the null pointer, the external file name is not returned. If \p offset or \p size are null pointers then the corresponding information is not returned. \note On Windows, off_t is typically a 32-bit signed long value, which limits the valid offset that can be returned to 2 GiB.

Returns:

\herr_t \details H5Pget_fill_value() returns the dataset fill value defined in the dataset creation property list \p plist_id. The fill value is returned through the \p value pointer and will be converted to the datatype specified by \p type_id. This datatype may differ from the fill value datatype in the property list, but the HDF5 library must be able to convert between the two datatypes. If the fill value is undefined, i.e., set to NULL in the property list, H5Pget_fill_value() will return an error. H5Pfill_value_defined() should be used to check for this condition before H5Pget_fill_value() is called. Memory must be allocated by the calling application. \note H5Pget_fill_value() is designed to coordinate with the dataset storage allocation time and fill value write time properties, which can be retrieved with the functions H5Pget_alloc_time() and H5Pget_fill_time(), respectively.

Returns:

Returns the length of the dataset name if successful; otherwise returns a negative value. \details H5Pget_virtual_dsetname() takes the dataset creation property list for the virtual dataset, \p dcpl_id, the mapping index, \p index, the size of the dataset name for a source dataset, \p size, and retrieves the name of the source dataset used in the mapping. Up to \p size characters of the dataset name are returned in \p name; additional characters, if any, are not returned to the user application. If the length of the dataset name, which determines the required value of \p size, is unknown, a preliminary call to H5Pget_virtual_dsetname() with the last two parameters set to NULL and zero respectively can be made. The return value of this call will be the size in bytes of the dataset name. That value, plus 1 for a NULL terminator, must then be assigned to \p size for a second H5Pget_virtual_dsetname() call, which will retrieve the actual dataset name. \see_virtual

\ingroup DCPL \brief Gets the filename of a source dataset used in the mapping \dcpl_id

Parameters:

index - [in] Mapping index. The value of \p index is 0 (zero) or greater and less than \p count (0 ≤ \p index < \p count), where \p count is the number of mappings returned by H5Pget_virtual_count().

name - [out] A buffer containing the name of the file containing the source dataset

size - [in] The size, in bytes, of the name buffer. Must be the size of the filename in bytes plus 1 for a NULL terminator

Returns:

Returns the length of the filename if successful; otherwise returns a negative value. \details H5Pget_virtual_filename() takes the dataset creation property list for the virtual dataset, \p dcpl_id, the mapping index, \p index, the size of the filename for a source dataset, \p size, and retrieves the name of the file for a source dataset used in the mapping. Up to \p size characters of the filename are returned in \p name; additional characters, if any, are not returned to the user application. If the length of the filename, which determines the required value of \p size, is unknown, a preliminary call to H5Pget_virtual_filename() with the last two parameters set to NULL and zero respectively can be made. The return value of this call will be the size in bytes of the filename. That value, plus 1 for a NULL terminator, must then be assigned to \p size for a second H5Pget_virtual_filename() call, which will retrieve the actual filename. \see_virtual

#H5D_ALLOC_TIME_EARLY	Allocate all space when the dataset is created (Default for compact datasets.)
#H5D_ALLOC_TIME_INCR	Allocate space incrementally, as data is written to the dataset (Default for chunked storage datasets.) \li Chunked datasets: Storage space allocation for each chunk is deferred until data is written to the chunk. \li Contiguous datasets: Incremental storage space allocation for contiguous data is treated as late allocation. \li Compact datasets: Incremental allocation is not allowed with compact datasets; H5Pset_alloc_time() will return an error.

Parameters:

Returns:

\herr_t \details H5Pset_chunk() sets the size of the chunks used to store a chunked layout dataset. This function is only valid for dataset creation property lists. The \p ndims parameter currently must be the same size as the rank of the dataset. The values of the \p dim array define the size of the chunks to store the dataset's raw data. The unit of measure for \p dim values is dataset elements. As a side-effect of this function, the layout of the dataset is changed to #H5D_CHUNKED, if it is not already so set. \note Chunk size cannot exceed the size of a fixed-size dataset. For example, a dataset consisting of a 5x4 fixed-size array cannot be defined with 10x10 chunks. Chunk maximums: - The maximum number of elements in a chunk is 2³²-1 which is equal to 4,294,967,295. If the number of elements in a chunk is set via H5Pset_chunk() to a value greater than 2³²-1, then H5Pset_chunk() will fail. - The maximum size for any chunk is 4GB. If a chunk that is larger than 4GB attempts to be written with H5Dwrite(), then H5Dwrite() will fail.

Parameters:

opts - [in] Edge chunk option flag. Valid values are: \li #H5D_CHUNK_DONT_FILTER_PARTIAL_CHUNKS When enabled, filters are not applied to partial edge chunks. When disabled, partial edge chunks are filtered. Enabling this option will improve performance when appending to the dataset and, when compression filters are used, prevent reallocation of these chunks. Datasets created with this option enabled will be inaccessible with HDF5 library versions before Release 1.10. Default: \e Disabled \li 0 (zero) Disables option; partial edge chunks will be compressed.

Returns:

\herr_t \details H5Pset_chunk_opts() sets the edge chunk option in the dataset creation property list \p dcpl_id. The available option is detailed in the parameters section. Only chunks that are not completely filled by the dataset’s dataspace are affected by this option.

Datasets created with the dataset creation property list \p dcpl_id will have their object headers minimized if the boolean flag \p minimize is set to TRUE. By setting \p minimize to TRUE, the library expects that no attributes will be added to the dataset. Attributes can be added, but they are appended with a continuation message, which can reduce performance.

Parameters:

name - [in] Name of an external file

offset - [in] Offset, in bytes, from the beginning of the file to the location in the file where the data starts

size - [in] Number of bytes reserved in the file for the data

Returns:

\herr_t \details The first call to H5Pset_external() sets the external storage property in the property list, thus designating that the dataset will be stored in one or more non-HDF5 file(s) external to the HDF5 file. This call also adds the file \p name as the first file in the list of external files. Subsequent calls to the function add the named file as the next file in the list. If a dataset is split across multiple files, then the files should be defined in order. The total size of the dataset is the sum of the \p size arguments for all the external files. If the total size is larger than the size of a dataset then the dataset can be extended (provided the data space also allows the extending). The \p size argument specifies the number of bytes reserved for data in the external file. If \p size is set to #H5F_UNLIMITED, the external file can be of unlimited size and no more files can be added to the external files list. If \p size is set to 0 (zero), no external file will actually be created. All of the external files for a given dataset must be specified with H5Pset_external() before H5Dcreate() is called to create the dataset. If one these files does not exist on the system when H5Dwrite() is called to write data to it, the library will create the file.

Returns:

\herr_t \details H5Pset_fill_value() sets the fill value for a dataset in the dataset creation property list. \p value is interpreted as being of datatype \p type_id. This datatype may differ from that of the dataset, but the HDF5 library must be able to convert \p value to the dataset datatype when the dataset is created. The default fill value is 0 (zero), which is interpreted according to the actual dataset datatype. Setting \p value to NULL indicates that the fill value is to be undefined. \note Applications sometimes write data only to portions of an allocated dataset. It is often useful in such cases to fill the unused space with a known fill value. This function allows the user application to set that fill value; the functions H5Dfill() and H5Pset_fill_time(), respectively, provide the ability to apply the fill value on demand or to set up its automatic application. \note A fill value should be defined so that it is appropriate for the application. While the HDF5 default fill value is 0 (zero), it is often appropriate to use another value. It might be useful, for example, to use a value that is known to be impossible for the application to legitimately generate. \note H5Pset_fill_value() is designed to work in concert with H5Pset_alloc_time() and H5Pset_fill_time(). H5Pset_alloc_time() and H5Pset_fill_time() govern the timing of dataset storage allocation and fill value write operations and can be important in tuning application performance. \note See H5Dcreate() for further cross-references.

\ingroup DCPL \brief Sets up use of the shuffle filter \dcpl_id{plist_id}

Returns:

\herr_t \par_compr_note \details H5Pset_shuffle() sets the shuffle filter, #H5Z_FILTER_SHUFFLE, in the dataset creation property list \p plist_id. The shuffle filter de-interlaces a block of data by reordering the bytes. All the bytes from one consistent byte position of each data element are placed together in one block; all bytes from a second consistent byte position of each data element are placed together a second block; etc. For example, given three data elements of a 4-byte datatype stored as 012301230123, shuffling will re-order data as 000111222333. This can be a valuable step in an effective compression algorithm because the bytes in each byte position are often closely related to each other and putting them together can increase the compression ratio. As implied above, the primary value of the shuffle filter lies in its coordinated use with a compression filter; it does not provide data compression when used alone. When the shuffle filter is applied to a dataset immediately prior to the use of a compression filter, the compression ratio achieved is often superior to that achieved by the use of a compression filter without the shuffle filter.

Returns:

\herr_t \par_compr_note \details H5Pset_nbit() sets the N-Bit filter, #H5Z_FILTER_NBIT, in the dataset creation property list \p plist_id. The HDF5 user can create an N-Bit datatype with the following code:

          hid_t nbit_datatype = H5Tcopy(H5T_STD_I32LE);
          H5Tset_precision(nbit_datatype, 16);
          H5Tset_offset(nbit_datatype, 4);
          

In memory, one value of the N-Bit datatype in the above example will be stored on a little-endian machine as follows:

byte 3	byte 2	byte 1	byte 0
????????	????SPPP	PPPPPPPP	PPPP????

Note: S - sign bit, P - significant bit, ? - padding bit; For signed integer, the sign bit is included in the precision. When data of the above datatype is stored on disk using the N-bit filter, all padding bits are chopped off and only significant bits are stored. The values on disk will be something like:

1st value	2nd value	...
SPPPPPPPPPPPPPPP	SPPPPPPPPPPPPPPP	...

The N-Bit filter is used effectively for compressing data of an N-Bit datatype as well as a compound and an array datatype with N-Bit fields. However, the datatype classes of the N-Bit datatype or the N-Bit field of the compound datatype or the array datatype are limited to integer or floating-point. The N-Bit filter supports complex situations where a compound datatype contains member(s) of a compound datatype or an array datatype that has a compound datatype as the base type. However, it does not support the situation where an array datatype has a variable-length or variable-length string as its base datatype. The filter does support the situation where a variable-length or variable-length string is a member of a compound datatype. The N-Bit filter allows all other HDF5 datatypes (such as time, string, bitfield, opaque, reference, enum, and variable length) to pass through as a no-op. Like other I/O filters supported by the HDF5 library, application using the N-Bit filter must store data with chunked storage. By nature, the N-Bit filter should not be used together with other I/O filters.

\ingroup DCPL \brief Sets up the use of the scale-offset filter \dcpl_id{plist_id}

Parameters:

scale_type - [in] Flag indicating compression method

scale_factor - [in] Parameter related to scale. Must be non-negative

Returns:

\herr_t \par_compr_note \details H5Pset_scaleoffset() sets the scale-offset filter, #H5Z_FILTER_SCALEOFFSET, for a dataset. Generally speaking, scale-offset compression performs a scale and/or offset operation on each data value and truncates the resulting value to a minimum number of bits (MinBits) before storing it. The current scale-offset filter supports integer and floating-point datatypes. For an integer datatype, the parameter \p scale_type should be set to #H5Z_SO_INT (2). The parameter \p scale_factor denotes MinBits. If the user sets it to H5Z_SO_INT_MINBITS_DEFAULT (0), the filter will calculate MinBits. If \p scale_factor is set to a positive integer, the filter does not do any calculation and just uses the number as MinBits. However, if the user gives a MinBits that is less than what would be generated by the filter, the compression will be lossy. Also, the MinBits supplied by the user cannot exceed the number of bits to store one value of the dataset datatype. For a floating-point datatype, the filter adopts the GRiB data packing mechanism, which offers two alternate methods: E-scaling and D-scaling. Both methods are lossy compression. If the parameter \p scale_type is set to #H5Z_SO_FLOAT_DSCALE (0), the filter will use the D-scaling method; if it is set to #H5Z_SO_FLOAT_ESCALE (1), the filter will use the E-scaling method. Since only the D-scaling method is implemented, \p scale_type should be set to #H5Z_SO_FLOAT_DSCALE or 0. When the D-scaling method is used, the original data is "D" scaled — multiplied by 10 to the power of \p scale_factor, and the "significant" part of the value is moved to the left of the decimal point. Care should be taken in setting the decimal \p scale_factor so that the integer part will have enough precision to contain the appropriate information of the data value. For example, if \p scale_factor is set to 2, the number 104.561 will be 10456.1 after "D" scaling. The last digit 1 is not "significant" and is thrown off in the process of rounding. The user should make sure that after "D" scaling and rounding, the data values are within the range that can be represented by the integer (same size as the floating-point type). Valid values for scale_type are as follows:

#H5Z_SO_FLOAT_DSCALE (0)	Floating-point type, using variable MinBits method
#H5Z_SO_FLOAT_ESCALE (1)	Floating-point type, using fixed MinBits method
#H5Z_SO_INT (2)	Integer type

The meaning of \p scale_factor varies according to the value assigned to \p scale_type:

\p scale_type value	\p scale_factor description
#H5Z_SO_FLOAT_DSCALE	Denotes the decimal scale factor for D-scaling and can be positive, negative or zero. This is the current implementation of the library.
#H5Z_SO_FLOAT_ESCALE	Denotes MinBits for E-scaling and must be a positive integer. This is not currently implemented by the library.
#H5Z_SO_INT	Denotes MinBits and it should be a positive integer or #H5Z_SO_INT_MINBITS_DEFAULT (0). If it is less than 0, the library will reset it to 0 since it is not implemented.

Like other I/O filters supported by the HDF5 library, an application using the scale-offset filter must store data with chunked storage.

options_mask - [in] A bit-mask conveying the desired SZIP options; Valid values are #H5_SZIP_EC_OPTION_MASK and #H5_SZIP_NN_OPTION_MASK.

pixels_per_block - [in] The number of pixels or data elements in each data block

Returns:

\herr_t \par_compr_note \details H5Pset_szip() sets an SZIP compression filter, #H5Z_FILTER_SZIP, for a dataset. SZIP is a compression method designed for use with scientific data. Before proceeding, all users should review the “Limitations” section below. Users familiar with SZIP outside the HDF5 context may benefit from reviewing the Note “For Users Familiar with SZIP in Other Contexts” below. In the text below, the term pixel refers to an HDF5 data element. This terminology derives from SZIP compression's use with image data, where pixel referred to an image pixel. The SZIP \p bits_per_pixel value (see Note, below) is automatically set, based on the HDF5 datatype. SZIP can be used with atomic datatypes that may have size of 8, 16, 32, or 64 bits. Specifically, a dataset with a datatype that is 8-, 16-, 32-, or 64-bit signed or unsigned integer; char; or 32- or 64-bit float can be compressed with SZIP. See Note, below, for further discussion of the SZIP \p bits_per_pixel setting. SZIP options are passed in an options mask, \p options_mask, as follows.

Option	Description (Mutually exclusive; select one.)
#H5_SZIP_EC_OPTION_MASK	Selects entropy coding method
#H5_SZIP_NN_OPTION_MASK	Selects nearest neighbor coding method

The following guidelines can be used in determining which option to select: - The entropy coding method, the EC option specified by #H5_SZIP_EC_OPTION_MASK, is best suited for data that has been processed. The EC method works best for small numbers. - The nearest neighbor coding method, the NN option specified by #H5_SZIP_NN_OPTION_MASK, preprocesses the data then the applies EC method as above. Other factors may affect results, but the above criteria provides a good starting point for optimizing data compression. SZIP compresses data block by block, with a user-tunable block size. This block size is passed in the parameter \p pixels_per_block and must be even and not greater than 32, with typical values being 8, 10, 16, or 32. This parameter affects compression ratio; the more pixel values vary, the smaller this number should be to achieve better performance. In HDF5, compression can be applied only to chunked datasets. If \p pixels_per_block is bigger than the total number of elements in a dataset chunk, H5Pset_szip() will succeed but the subsequent call to H5Dcreate() will fail; the conflict can be detected only when the property list is used. To achieve optimal performance for SZIP compression, it is recommended that a chunk's fastest-changing dimension be equal to N times \p pixels_per_block where N is the maximum number of blocks per scan line allowed by the SZIP library. In the current version of SZIP, N is set to 128. SZIP compression is an optional HDF5 filter. \b Limitations: - SZIP compression cannot be applied to compound, array, variable-length, enumeration, or any other user-defined datatypes. If an SZIP filter is set in a dataset creation property list used to create a dataset containing a non-allowed datatype, the call to H5Dcreate() will fail; the conflict can be detected only when the property list is used. - Users should be aware that there are factors that affect one’s rights and ability to use SZIP compression by reviewing the SZIP copyright notice. \note \b For \b Users \b Familiar \b with \b SZIP \b in \b Other \b Contexts: \note The following notes are of interest primarily to those who have used SZIP compression outside of the HDF5 context. In non-HDF5 applications, SZIP typically requires that the user application supply additional parameters: - \p pixels_in_object, the number of pixels in the object to be compressed - \p bits_per_pixel, the number of bits per pixel - \p pixels_per_scanline, the number of pixels per scan line \note These values need not be independently supplied in the HDF5 environment as they are derived from the datatype and dataspace, which are already known. In particular, HDF5 sets \p pixels_in_object to the number of elements in a chunk and \p bits_per_pixel to the size of the element or pixel datatype. \note The following algorithm is used to set \p pixels_per_scanline: - If the size of a chunk's fastest-changing dimension, size, is greater than 4K, set \p pixels_per_scanline to 128 times \p pixels_per_block. - If size is less than 4K but greater than \p pixels_per_block, set \p pixels_per_scanline to the minimum of size and 128 times \p pixels_per_block. - If size is less than \p pixels_per_block but greater than the number elements in the chunk, set \p pixels_per_scanline to the minimum of the number elements in the chunk and 128 times \p pixels_per_block. \note The HDF5 datatype may have precision that is less than the full size of the data element, e.g., an 11-bit integer can be defined using H5Tset_precision(). To a certain extent, SZIP can take advantage of the precision of the datatype to improve compression: - If the HDF5 datatype size is 24-bit or less and the offset of the bits in the HDF5 datatype is zero (see H5Tset_offset() or H5Tget_offset()), the data is the in lowest N bits of the data element. In this case, the SZIP \p bits_per_pixel is set to the precision of the HDF5 datatype. - If the offset is not zero, the SZIP \p bits_per_pixel will be set to the number of bits in the full size of the data element. - If the HDF5 datatype precision is 25-bit to 32-bit, the SZIP \p bits_per_pixel will be set to 32. - If the HDF5 datatype precision is 33-bit to 64-bit, the SZIP \p bits_per_pixel will be set to 64. \note HDF5 always modifies the options mask provided by the user to set up usage of RAW_OPTION_MASK, ALLOW_K13_OPTION_MASK, and one of LSB_OPTION_MASK or MSB_OPTION_MASK, depending on endianness of the datatype.

Returns:

\herr_t \details H5Pset_virtual() maps elements of the virtual dataset (VDS) described by the virtual dataspace identifier \p vspace_id to the elements of the source dataset described by the source dataset dataspace identifier \p src_space_id. The source dataset is identified by the name of the file where it is located, \p src_file_name, and the name of the dataset, \p src_dset_name. \par C-style \c printf Formatting Statements: C-style \c printf formatting allows a pattern to be specified in the name of a source file or dataset. Strings for the file and dataset names are treated as literals except for the following substitutions:

\Code{"%%"}

Replaced with a single \Code{"%"} (percent) character.

"%b"

Where "" is the virtual dataset dimension axis (0-based) and \Code{"b"} indicates that the block count of the selection in that dimension should be used. The full expression (for example, \Code{"%0b"}) is replaced with a single numeric value when the mapping is evaluated at VDS access time. Example code for many source and virtual dataset mappings is available in the "Examples of Source to Virtual Dataset Mapping" chapter in the RFC: HDF5 Virtual Dataset.

If the printf form is used for the source file or dataset names, the selection in the source dataset’s dataspace must be fixed-size. \par Source File Resolutions: When a source dataset residing in a different file is accessed, the library will search for the source file \p src_file_name as described below: \li If \p src_file_name is a \Code{"."} (period) then it refers to the file containing the virtual dataset. \li If \p src_file_name is a relative pathname, the following steps are performed: - The library will get the prefix(es) set in the environment variable \c HDF5_VDS_PREFIX and will try to prepend each prefix to \p src_file_name to form a new \p src_file_name. If the new \p src_file_name does not exist or if \c HDF5_VDS_PREFIX is not set, the library will get the prefix set via H5Pset_virtual_prefix() and prepend it to \p src_file_name to form a new \p src_file_name. If the new \p src_file_name does not exist or no prefix is being set by H5Pset_virtual_prefix() then the path of the file containing the virtual dataset is obtained. This path can be the absolute path or the current working directory plus the relative path of that file when it is created/opened. The library will prepend this path to \p src_file_name to form a new \p src_file_name. - If the new \p src_file_name does not exist, then the library will look for \p src_file_name and will return failure/success accordingly. \li If \p src_file_name is an absolute pathname, the library will first try to find \p src_file_name. If \p src_file_name does not exist, \p src_file_name is stripped of directory paths to form a new \p src_file_name. The search for the new \p src_file_name then follows the same steps as described above for a relative pathname. See examples below illustrating how \p src_file_name is stripped to form a new \p src_file_name. \par Note that \p src_file_name is considered to be an absolute pathname when the following condition is true: \li For Unix, the first character of \p src_file_name is a slash (\Code{/}).\n For example, consider a \p src_file_name of \Code{/tmp/A.h5}. If that source file does not exist, the new \p src_file_name after stripping will be \Code{A.h5}. \li For Windows, there are 6 cases: 1. \p src_file_name is an absolute drive with absolute pathname.\n For example, consider a \p src_file_name of \Code{/tmp/A.h5}. If that source file does not exist, the new \p src_file_name after stripping will be \Code{A.h5}. 2. \p src_file_name is an absolute pathname without specifying drive name.\n For example, consider a \p src_file_name of \Code{/tmp/A.h5}. If that source file does not exist, the new \p src_file_name after stripping will be \Code{A.h5}. 3. \p src_file_name is an absolute drive with relative pathname.\n For example, consider a \p src_file_name of \Code{/tmp/A.h5}. If that source file does not exist, the new \p src_file_name after stripping will be \Code{tmp/A.h5}. 4. \p src_file_name is in UNC (Uniform Naming Convention) format with server name, share name, and pathname.\n For example, consider a \p src_file_name of \Code{/tmp/A.h5}. If that source file does not exist, the new \p src_file_name after stripping will be \Code{A.h5}. 5. \p src_file_name is in Long UNC (Uniform Naming Convention) format with server name, share name, and pathname.\n For example, consider a \p src_file_name of \Code{/tmp/A.h5}. If that source file does not exist, the new \p src_file_name after stripping will be \Code{A.h5}. 6. \p src_file_name is in Long UNC (Uniform Naming Convention) format with an absolute drive and an absolute pathname.\n For example, consider a \p src_file_name of \Code{/tmp/A.h5}. If that source file does not exist, the new \p src_file_name after stripping will be \Code{A.h5}

\ingroup DAPL \brief Retrieves the values of the append property that is set up in the dataset access property list \dapl_id

Parameters:

dims - [in] The number of elements for \p boundary

boundary - [in] The dimension sizes used to determine the boundary

func - [in] The user-defined callback function

udata - [in] The user-defined input data

Returns:

\herr_t \details H5Pget_append_flush() obtains the following information from the dataset access property list, \p dapl_id. \p boundary consists of the sizes set up in the access property list that are used to determine when a dataset dimension size hits the boundary. Only at most \p dims boundary sizes are retrieved, and \p dims will not exceed the corresponding value that is set in the property list. \p func is the user-defined callback function to invoke when a dataset’s appended dimension size reaches a boundary and \p udata is the user-defined input data for the callback function.

Parameters:

prefix - [in,out] Dataset external storage prefix in UTF-8 or ASCII (\em Path and \em filename must be ASCII on Windows systems.)

size - [in] Size of prefix buffer in bytes

Returns:

Returns the size of \p prefix and the prefix string will be stored in \p prefix if successful. Otherwise returns a negative value and the contents of \p prefix will be undefined. \details H5Pget_efile_prefix() retrieves the file system path prefix for locating external files associated with a dataset that uses external storage. This will be the value set with H5Pset_efile_prefix() or the HDF5 library’s default. The value of \p size is the size in bytes of the prefix, including the NULL terminator. If the size is unknown, a preliminary H5Pget_elink_prefix() call with the pointer \p prefix set to NULL will return the size of the prefix without the NULL terminator. The \p prefix buffer must be allocated by the caller. In a call that retrieves the actual prefix, that buffer must be of the size specified in \p size. \note See H5Pset_efile_prefix() for a more complete description of file location behavior and for notes on the use of the HDF5_EXTFILE_PREFIX environment variable.

boundary - [in] The dimension sizes used to determine the boundary

func - [in] The user-defined callback function

udata - [in] The user-defined input data

Returns:

\herr_t \details H5Pset_append_flush() sets the following two actions to perform for a dataset associated with the dataset access property list \p dapl_id: \li Call the callback function \p func set in the property list \li Flush the dataset associated with the dataset access property list When a user is appending data to a dataset via H5DOappend() and the dataset’s newly extended dimension size hits a specified boundary, the library will perform the first action listed above. Upon return from the callback function, the library will then perform the second action listed above and return to the user. If no boundary is hit or set, the two actions above are not invoked. The specified boundary is indicated by the parameter \p boundary. It is a 1-dimensional array with \p ndims elements, which should be the same as the rank of the dataset’s dataspace. While appending to a dataset along a particular dimension index via H5Dappend(), the library determines a boundary is reached when the resulting dimension size is divisible by \p boundary[index]. A zero value for \p boundary[index] indicates no boundary is set for that dimension index. The setting of this property will apply only for a chunked dataset with an extendible dataspace. A dataspace is extendible when it is defined with either one of the following: \li A dataspace with fixed current and maximum dimension sizes \li A dataspace with at least one unlimited dimension for its maximum dimension size When creating or opening a chunked dataset, the library will check whether the boundary as specified in the access property list is set up properly. The library will fail the dataset create or open if the following conditions are true: \li \p ndims, the number of elements for boundary, is not the same as the rank of the dataset’s dataspace. \li A non-zero boundary value is specified for a non-extendible dimension. The callback function \p func must conform to the following prototype: \snippet H5Dpublic.h H5D_append_cb_t_snip The parameters of the callback function, per the above prototype, are defined as follows: \li \p dataset_id is the dataset identifier. \li \p cur_dims is the dataset’s current dimension sizes when a boundary is hit. \li \p user_data is the user-defined input data.

\ingroup DAPL \brief Sets the raw data chunk cache parameters \dapl_id

Parameters:

rdcc_nslots - [in] The number of chunk slots in the raw data chunk cache for this dataset. Increasing this value reduces the number of cache collisions, but slightly increases the memory used. Due to the hashing strategy, this value should ideally be a prime number. As a rule of thumb, this value should be at least 10 times the number of chunks that can fit in \p rdcc_nbytes bytes. For maximum performance, this value should be set approximately 100 times that number of chunks. The default value is 521. If the value passed is #H5D_CHUNK_CACHE_NSLOTS_DEFAULT, then the property will not be set on \p dapl_id and the parameter will come from the file access property list used to open the file.

rdcc_nbytes - [in] The total size of the raw data chunk cache for this dataset. In most cases increasing this number will improve performance, as long as you have enough free memory. The default size is 1 MB. If the value passed is #H5D_CHUNK_CACHE_NBYTES_DEFAULT, then the property will not be set on \p dapl_id and the parameter will come from the file access property list.

rdcc_w - [in] 0 The chunk preemption policy for this dataset. This must be between 0 and 1 inclusive and indicates the weighting according to which chunks which have been fully read or written are penalized when determining which chunks to flush from cache. A value of 0 means fully read or written chunks are treated no differently than other chunks (the preemption is strictly LRU) while a value of 1 means fully read or written chunks are always preempted before other chunks. If your application only reads or writes data once, this can be safely set to 1. Otherwise, this should be set lower, depending on how often you re-read or re-write the same data. The default value is 0.75. If the value passed is #H5D_CHUNK_CACHE_W0_DEFAULT, then the property will not be set on \p dapl_id and the parameter will come from the file access property list.

Returns:

\herr_t \details H5Pset_chunk_cache() sets the number of elements, the total number of bytes, and the preemption policy value in the raw data chunk cache on a dataset access property list. After calling this function, the values set in the property list will override the values in the file's file access property list. The raw data chunk cache inserts chunks into the cache by first computing a hash value using the address of a chunk, then using that hash value as the chunk's index into the table of cached chunks. The size of this hash table, i.e., and the number of possible hash values, is determined by the \p rdcc_nslots parameter. If a different chunk in the cache has the same hash value, this causes a collision, which reduces efficiency. If inserting the chunk into cache would cause the cache to be too big, then the cache is pruned according to the \p rdcc_w0 parameter. \b Motivation: H5Pset_chunk_cache() is used to adjust the chunk cache parameters on a per-dataset basis, as opposed to a global setting for the file using H5Pset_cache(). The optimum chunk cache parameters may vary widely with different data layout and access patterns, so for optimal performance they must be set individually for each dataset. It may also be beneficial to reduce the size of the chunk cache for datasets whose performance is not important in order to save memory space. \b Example \b Usage: The following code sets the chunk cache to use a hash table with 12421 elements and a maximum size of 16 MB, while using the preemption policy specified for the entire file: \Code{ H5Pset_chunk_cache(dapl_id, 12421, 16*1024*1024, H5D_CHUNK_CACHE_W0_DEFAULT);} \b Usage \b Notes: The chunk cache size is a property for accessing a dataset and is not stored with a dataset or a file. To guarantee the same chunk cache settings each time the dataset is opened, call H5Dopen() with a dataset access property list where the chunk cache size is set by calling H5Pset_chunk_cache() for that property list. The property list can be used for multiple accesses in the same application. For files where the same chunk cache size will be appropriate for all or most datasets, H5Pset_cache() can be called with a file access property list to set the chunk cache size for accessing all datasets in the file. Both methods can be used in combination, in which case the chunk cache size set by H5Pset_cache() will apply except for specific datasets where H5Dopen() is called with dataset property list with the chunk cache size set by H5Pset_chunk_cache(). In the absence of any cache settings, H5Dopen() will by default create a 1 MB chunk cache for the opened dataset. If this size happens to be appropriate, no call will be needed to either function to set the chunk cache size. It is also possible that a change in access pattern for later access to a dataset will change the appropriate chunk cache size.

\ingroup DAPL \brief Sets the external dataset storage file prefix in the dataset access property list \dapl_id

Parameters:

prefix - [in] Dataset external storage prefix in UTF-8 or ASCII (Path and filename must be ASCII on Windows systems.)

Returns:

\herr_t \details H5Pset_efile_prefix() sets the prefix used to locate raw data files for a dataset that uses external storage. This prefix can provide either an absolute path or a relative path to the external files. H5Pset_efile_prefix() is used in conjunction with H5Pset_external() to control the behavior of the HDF5 library when searching for the raw data files associated with a dataset that uses external storage: \li The default behavior of the library is to search for the dataset’s external storage raw data files in the same directory as the HDF5 file which contains the dataset. \li If the prefix is set to an absolute path, the target directory will be searched for the dataset’s external storage raw data files. \li If the prefix is set to a relative path, the target directory, relative to the current working directory, will be searched for the dataset’s external storage raw data files. \li If the prefix is set to a relative path that begins with the special token ${ORIGIN}, that directory, relative to the HDF5 file containing the dataset, will be searched for the dataset’s external storage raw data files. The HDF5_EXTFILE_PREFIX environment variable can be used to override the above behavior (the environment variable supersedes the API call). Setting the variable to a path string and calling H5Dcreate() or H5Dopen() is the equivalent of calling H5Pset_efile_prefix() and calling the same create or open function. The environment variable is checked at the time of the create or open action and copied so it can be safely changed after the H5Dcreate() or H5Dopen() call. Calling H5Pset_efile_prefix() with \p prefix set to NULL or the empty string returns the search path to the default. The result would be the same as if H5Pset_efile_prefix() had never been called. \note If the external file prefix is not an absolute path and the HDF5 file is moved, the external storage files will also need to be moved so they can be accessed at the new location. \note As stated above, the use of the HDF5_EXTFILE_PREFIX environment variable overrides any property list setting. H5Pset_efile_prefix() and H5Pget_efile_prefix(), being property functions, set and retrieve only the property list setting; they are unaware of the environment variable. \note On Windows, the prefix must be an ASCII string since the Windows standard C library’s I/O functions cannot handle UTF-8 file names.

\ingroup DXPL \brief Retrieves a data transform expression

Parameters:

plist_id - [in] Identifier of the property list or class

expression - [out] Pointer to memory where the transform expression will be copied

size - [in] Number of bytes of the transform expression to copy to

Returns:

Success: the size of the transform expression. Failure: a negative value. \details H5Pget_data_transform() retrieves the data transform expression previously set in the dataset transfer property list \p plist_id by H5Pset_data_transform(). H5Pget_data_transform() can be used to both retrieve the transform expression and query its size. If \p expression is non-NULL, up to \p size bytes of the data transform expression are written to the buffer. If \p expression is NULL, \p size is ignored, and the function does not write anything to the buffer. The function always returns the size of the data transform expression. If 0 is returned for the size of the expression, no data transform expression exists for the property list. If an error occurs, the buffer pointed to by \p expression is unchanged, and the function returns a negative value.

Parameters:

size - [in] Size, in bytes, of the type conversion and background buffers

tconv - [in] Pointer to application-allocated type conversion buffer

bkg - [in] Pointer to application-allocated background buffer

Returns:

\herr_t \details Given a dataset transfer property list, H5Pset_buffer() sets the maximum size for the type conversion buffer and background buffer and optionally supplies pointers to application-allocated buffers. If the buffer size is smaller than the entire amount of data being transferred between the application and the file, and a type conversion buffer or background buffer is required, then strip mining will be used. Note that there are minimum size requirements for the buffer. Strip mining can only break the data up along the first dimension, so the buffer must be large enough to accommodate a complete slice that encompasses all of the remaining dimensions. For example, when strip mining a \Code{100x200x300} hyperslab of a simple data space, the buffer must be large enough to hold \Code{1x200x300} data elements. When strip mining a \Code{100x200x300x150} hyperslab of a simple data space, the buffer must be large enough to hold \Code{1x200x300x150} data elements. If \p tconv and/or \p bkg are null pointers, then buffers will be allocated and freed during the data transfer. The default value for the maximum buffer is 1 MiB.

Returns:

\herr_t \details H5Pset_data_transform() sets the data transform to be used for reading and writing data. This function operates on the dataset transfer property list \p plist_id. The \p expression parameter is a string containing an algebraic expression, such as \Code{(5/9.0)*(x-32)} or \Code{x*(x-5)}. When a dataset is read or written with this property list, the transform expression is applied with the \c x being replaced by the values in the dataset. When reading data, the values in the file are not changed and the transformed data is returned to the user. Data transforms can only be applied to integer or floating-point datasets. Order of operations is obeyed and the only supported operations are +, -, *, and /. Parentheses can be nested arbitrarily and can be used to change precedence. When writing data back to the dataset, the transformed data is written to the file and there is no way to recover the original values to which the transform was applied.

Parameters:

check - [in] Specifies whether error checking is enabled or disabled for dataset read operations

Returns:

\herr_t \details H5Pset_edc_check() sets the dataset transfer property list \p plist to enable or disable error detection when reading data. Whether error detection is enabled or disabled is specified in the \p check parameter. Valid values are #H5Z_ENABLE_EDC (default) and #H5Z_DISABLE_EDC. \note The initial error detection implementation, Fletcher32 checksum, supports error detection for chunked datasets only. \attention The Fletcher32 EDC checksum filter, set with H5Pset_fletcher32(), was added in HDF5 Release 1.6.0. In the original implementation, however, the checksum value was calculated incorrectly on little-endian systems. The error was fixed in HDF5 Release 1.6.3.\n As a result of this fix, an HDF5 library of Release 1.6.0 through Release 1.6.2 cannot read a dataset created or written with Release 1.6.3 or later if the dataset was created with the checksum filter and the filter is enabled in the reading library. (Libraries of Release 1.6.3 and later understand the earlier error and compensate appropriately.)\n \Bold{Work-around:} An HDF5 library of Release 1.6.2 or earlier will be able to read a dataset created or written with the checksum filter by an HDF5 library of Release 1.6.3 or later if the checksum filter is disabled for the read operation. This can be accomplished via an H5Pset_edc_check() call with the value #H5Z_DISABLE_EDC in the second parameter. This has the obvious drawback that the application will be unable to verify the checksum, but the data does remain accessible.

Parameters:

Returns:

\herr_t \details H5Pset_hyper_vector_size() sets the number of I/O vectors to be accumulated in memory before being issued to the lower levels of the HDF5 library for reading or writing the actual data. The I/O vectors are hyperslab offset and length pairs and are generated during hyperslab I/O. The number of I/O vectors is passed in \p size to be set in the dataset transfer property list \p plist_id. \p size must be greater than 1 (one). H5Pset_hyper_vector_size() is an I/O optimization function; increasing vector_size should provide better performance, but the library will use more memory during hyperslab I/O. The default value of \p size is 1024.

Deprecated. This function is deprecated as it no longer has any effect; compound datatype field preservation is now core functionality in the HDF5 library. \details H5Pset_preserve() sets the dataset transfer property list status to \c 1 or \c 0. When reading or writing compound datatypes and the destination is partially initialized and the read/write is intended to initialize the other members, one must set this property to \c 1. Otherwise the I/O pipeline treats the destination datapoints as completely uninitialized.

Parameters:

selection_io_mode - [in] The selection I/O mode to be set

Returns:

\herr_t \details H5Pset_selection_io() sets the selection I/O mode \p selection_io_mode in the dataset transfer property list \p plist_id. This can be used to enable collective I/O with type conversion, or with custom VFDs that support vector or selection I/O. Values that can be set in \p selection_io_mode: \snippet this H5D_selection_io_mode_t_snip \click4more \note The library may not perform selection I/O as it asks for if the layout callback determines that it is not feasible to do so. Please refer to H5Pget_no_selection_io_cause() for details. When used with type conversion, selection I/O requires the type conversion buffer (and the background buffer if applicable) be large enough to hold the entirety of the data involved in the I/O. For read operations, the library will use the application's read buffer as the type conversion buffer if the memory type is not smaller than the file type, eliminating the need for a separate type conversion buffer (a background buffer may still be required). For write operations, the library will similarly use the write buffer as a type conversion buffer, but only if H5Pset_modify_write_buf() is used to allow the library to modify the contents of the write buffer.

\ingroup DXPL \brief Retrieves the cause for not performing selection or vector I/O on the last parallel I/O call \dxpl_id{plist_id}

Parameters:

no_selection_io_cause - [out] A bitwise set value indicating the relevant causes that prevented selection I/O from being performed

Returns:

\herr_t \par Motivation: A user can request selection I/O to be performed via a data transfer property list (DXPL). This can be used to enable collective I/O with type conversion, or with custom VFDs that support vector or selection I/O. However, there are conditions that can cause HDF5 to forgo selection or vector I/O and perform legacy (scalar) I/O instead. \details H5Pget_no_selection_io_cause() can be used to determine whether selection or vector I/O was applied for the last preceding I/O call. If selection or vector I/O was not used, this function retrieves the cause(s) that prevent selection or vector I/O to be performed on that I/O call. The properties retrieved by this function are set before I/O takes place and are retained even when I/O fails. If a selection I/O request falls back to vector I/O, that is not considered "breaking" selection I/O by this function, since vector I/O still passes all information to the file driver in a single callback. Valid values returned in \p no_selection_io_cause are listed as follows. If there are multiple causes, it is a bitwise OR of the relevant causes. - #H5D_SEL_IO_DISABLE_BY_API Selection I/O was not performed because the feature was disabled by the API - #H5D_SEL_IO_NOT_CONTIGUOUS_OR_CHUNKED_DATASET Selection I/O was not performed because the dataset was neither contiguous nor chunked - #H5D_SEL_IO_CONTIGUOUS_SIEVE_BUFFER Selection I/O was not performed because of sieve buffer for contiguous dataset - #H5D_SEL_IO_NO_VECTOR_OR_SELECTION_IO_CB Selection I/O was not performed because the VFD does not have vector or selection I/O callback - #H5D_SEL_IO_PAGE_BUFFER Selection I/O was not performed because of page buffer - #H5D_SEL_IO_DATASET_FILTER Selection I/O was not performed because of dataset filters - #H5D_SEL_IO_CHUNK_CACHE Selection I/O was not performed because of chunk cache - #H5D_SEL_IO_TCONV_BUF_TOO_SMALL Selection I/O was not performed because the type conversion buffer is too small - #H5D_SEL_IO_BKG_BUF_TOO_SMALL Selection I/O was not performed because the type conversion background buffer is too small - #H5D_SEL_IO_DEFAULT_OFF Selection I/O was not performed because the selection I/O mode is DEFAULT and the library chose it to be off for this case

Parameters:

est_name_len - [in] Estimated average length of link names

Returns:

\herr_t \details H5Pset_est_link_info() inserts two settings into the group creation property list plist_id: the estimated number of links that are expected to be inserted into a group created with the property list and the estimated average length of those link names. The estimated number of links is passed in \p est_num_entries. The limit for \p est_num_entries is 64 K. The estimated average length of the anticipated link names is passed in \p est_name_len. The limit for \p est_name_len is 64 K. The values for these two settings are multiplied to compute the initial local heap size (for old-style groups, if the local heap size hint is not set) or the initial object header size for (new-style compact groups; see \ref_group_impls). Accurately setting these parameters will help reduce wasted file space. If a group is expected to have many links and to be stored in dense format, set \p est_num_entries to 0 (zero) for maximum efficiency. This will prevent the group from being created in the compact format. See \ref_group_impls for a discussion of the available types of HDF5 group structures.

\ingroup GCPL \brief Sets creation order tracking and indexing for links in a group

Parameters:

plist_id - [in] Group or file creation property list identifier

crt_order_flags - [out] Creation order flag(s)

Returns:

\herr_t \details H5Pset_link_creation_order() sets flags for tracking and indexing links on creation order in groups created with the group (or file) creation property list \p plist_id. \p crt_order_flags contains flags with the following meanings:

#H5P_CRT_ORDER_TRACKED	Link creation order is tracked but not necessarily indexed
#H5P_CRT_ORDER_INDEXED	Link creation order is indexed (requires #H5P_CRT_ORDER_TRACKED)

The default behavior is that links are tracked and indexed by name, and link creation order is neither tracked nor indexed. The name is always the primary index for links in a group. H5Pset_link_creation_order() can be used to set link creation order tracking, or to set link creation order tracking and indexing. If (#H5P_CRT_ORDER_TRACKED | #H5P_CRT_ORDER_INDEXED) is specified for \p crt_order_flags, then links will be tracked and indexed by creation order. The creation order is added as a secondary index and enables faster queries and iterations by creation order. If just #H5P_CRT_ORDER_TRACKED is specified for \p crt_order_flags, then links will be tracked by creation order, but not indexed by creation order. Queries and iterations by creation order will work but will be much slower for large groups than if #H5P_CRT_ORDER_INDEXED had been included. \note If a creation order index is to be built, it must be specified in the group creation property list. HDF5 currently provides no mechanism to turn on link creation order tracking at group creation time and to build the index later.

\ingroup GCPL \brief Specifies the anticipated maximum size of a local heap \gcpl_id{plist_id}

Parameters:

size_hint - [in] Anticipated maximum size in bytes of local heap

Returns:

\herr_t \details H5Pset_local_heap_size_hint() is used with original-style HDF5 groups (see “Motivation” below) to specify the anticipated maximum local heap size, size_hint, for groups created with the group creation property list \p plist_id. The HDF5 library then uses \p size_hint to allocate contiguous local heap space in the file for each group created with \p plist_id. For groups with many members or very few members, an appropriate initial value of \p size_hint would be the anticipated number of group members times the average length of group member names, plus a small margin:

          size_hint = max_number_of_group_members  *
                      (average_length_of_group_member_link_names + 2)
          

If it is known that there will be groups with zero members, the use of a group creation property list with \p size_hint set to to 1 (one) will guarantee the smallest possible local heap for each of those groups. Setting \p size_hint to zero (0) causes the library to make a reasonable estimate for the default local heap size. \par Motivation: In situations where backward-compatibility is required, specifically, when libraries prior to HDF5 Release 1.8.0 may be used to read the file, groups must be created and maintained in the original style. This is HDF5’s default behavior. If backward compatibility with pre-1.8.0 libraries is not a concern, greater efficiencies can be obtained with the new-format compact and indexed groups. See Group implementations in HDF5 in the \ref H5G API introduction (at the bottom).\n H5Pset_local_heap_size_hint() is useful for tuning file size when files contain original-style groups with either zero members or very large numbers of members.\n The original style of HDF5 groups, the only style available prior to HDF5 Release 1.8.0, was well-suited for moderate-sized groups but was not optimized for either very small or very large groups. This original style remains the default, but two new group implementations were introduced in HDF5 Release 1.8.0: compact groups to accommodate zero to small numbers of members and indexed groups for thousands or tens of thousands of members ... or millions, if that's what your application requires.\n The local heap size hint, \p size_hint, is a performance tuning parameter for original-style groups. As indicated above, an HDF5 group may have zero, a handful, or tens of thousands of members. Since the original style of HDF5 groups stores the metadata for all of these group members in a uniform format in a local heap, the size of that metadata (and hence, the size of the local heap) can vary wildly from group to group. To intelligently allocate space and to avoid unnecessary fragmentation of the local heap, it can be valuable to provide the library with a hint as to the local heap’s likely eventual size. This can be particularly valuable when it is known that a group will eventually have a great many members. It can also be useful in conserving space in a file when it is known that certain groups will never have any members.

\ingroup LAPL \brief Sets the external link traversal file access flag in a link access property list \lapl_id

Parameters:

flags - [in] The access flag for external link traversal

Returns:

\herr_t \details H5Pset_elink_acc_flags() specifies the file access flag to use to open the target file of an external link. This allows read-only access of files reached through an external link in a file opened with write access, or vice-versa. Valid values for \p flags include: \li #H5F_ACC_RDWR - Causes files opened through external links to be opened with write access \li #H5F_ACC_RDONLY - Causes files opened through external links to be opened with read-only access \li #H5F_ACC_DEFAULT - Removes any external link file access flag setting from \p lapl_id, causing the file access flag setting to be taken from the parent file The library will normally use the file access flag used to open the parent file as the file access flag for the target file. This function provides a way to override that behavior. The external link traversal callback function set by H5Pset_elink_cb() can override the setting from H5Pset_elink_acc_flags(). Motivation: H5Pset_elink_acc_flags() is used to adjust the file access flag used to open files reached through external links. This may be useful to, for example, prevent modifying files accessed through an external link. Otherwise, the target file is opened with whatever flag was used to open the parent. Example Usage: The following code sets the link access property list \p lapl_id to open external link target files with read-only access:

         status = H5Pset_elink_acc_flags(lapl_id, H5F_ACC_RDONLY);

\ingroup LAPL \brief Sets the external link traversal callback function in a link access property list \lapl_id

Parameters:

func - [in] User-defined external link traversal callback function

op_data - [in] User-defined input data for the callback function

Returns:

\herr_t \details H5Pset_elink_cb() sets a user-defined external link traversal callback function in the link access property list \p lapl_id. The callback function \p func must conform to the prototype specified in #H5L_elink_traverse_t. The callback function may adjust the file access property list and file access flags to use when opening a file through an external link. The callback will be executed by the HDF5 library immediately before opening the target file. The callback will be made after the file access property list set by H5Pset_elink_fapl() and the file access flag set by H5Pset_elink_acc_flags() are applied, so changes made by this callback function will take precedence. \attention A file close degree property setting (H5Pset_fclose_degree()) in this callback function or an associated property list will be ignored. A file opened by means of traversing an external link is always opened with the weak file close degree property setting, #H5F_CLOSE_WEAK. Motivation: H5Pset_elink_cb() is used to specify a callback function that is executed by the HDF5 library when traversing an external link. This provides a mechanism to set specific access permissions, modify the file access property list, modify the parent or target file, or take any other user-defined action. This callback function is used in situations where the HDF5 library's default behavior is not suitable. Failure Modes: H5Pset_elink_cb() will fail if the link access property list identifier, \p lapl_id, is invalid or if the function pointer, \p func, is NULL. An invalid function pointer, \p func, will cause a segmentation fault or other failure when an attempt is subsequently made to traverse an external link. Example Usage: This example defines a callback function that prints the name of the target file every time an external link is followed, and sets this callback function on \p lapl_id.

\ingroup OCPYPL \brief Adds a path to the list of paths that will be searched in the destination file for a matching committed datatype

Parameters:

plist_id - [in] Object copy property list identifier

path - [in] The path to be added

Returns:

\herr_t \details H5Padd_merge_committed_dtype_path() adds a path, \p path, which points to a committed datatype, to the current list of suggested paths stored in the object copy property list \p plist_id. The search as described in the next paragraph is effective only if the #H5O_COPY_MERGE_COMMITTED_DTYPE_FLAG is enabled in the object copy property list via H5Pset_copy_object(). When copying a committed datatype, a dataset with a committed datatype, or an object with an attribute of a committed datatype, the default behavior of H5Ocopy() is to search for a matching committed datatype:

1. First search the list of suggested paths in the object copy property list.
2. Then, if no match has been found, search all the committed datatypes in the destination file.

The default Step 2 in this search process can be changed by setting a callback function (see H5Pset_mcdt_search_cb()). Two datatypes are determined equal if their descriptions are identical, in a manner similar to H5Tequal(). If either committed datatype has one or more attributes, then all attributes must be present in both committed datatypes and they must be identical. Two attributes are considered identical if their datatype description, dataspace, and raw data values are the same. However, if an attribute uses a committed datatype, that committed datatype’s attributes will not be compared. If a match is found, H5Ocopy() will perform the following in the destination file: \li For a committed datatype, the library will create a hard link to the found datatype. \li For a dataset that uses a committed datatype, the library will modify the copied dataset to use the found committed datatype as its datatype. \li For an object with an attribute of a committed datatype, the library will modify the copied object’s attribute to use the found committed datatype as its datatype. If no match is found, H5Ocopy() will perform the following in the destination file: \li For a committed datatype, the library will copy it as it would any other object, creating a named committed datatype at the destination. That is, the library will create a committed datatype that is accessible in the file by a unique path. \li For a dataset that uses a committed datatype, the library will copy the datatype as an anonymous committed datatype and use that as the dataset’s datatype. \li For an object with an attribute of a committed datatype, the library will copy the datatype as an anonymous committed datatype and use that as the attribute’s datatype. \b Motivation: H5Padd_merge_committed_dtype_path() provides a means to override the default behavior of H5Ocopy() when #H5O_COPY_MERGE_COMMITTED_DTYPE_FLAG is set in an object copy property list. H5Padd_merge_committed_dtype_path() is the mechanism for suggesting search paths where H5Ocopy() will look for a matching committed datatype. This can be substantially faster than the default approach of searching the entire destination file for a match. \b Example \b Usage: This example adds two paths to the object copy property list. H5Ocopy() will search the two suggested paths for a match before searching all the committed datatypes in the destination file.

     int main(void) {
     hid_t ocpypl_id = H5Pcreate(H5P_OBJECT_COPY);

        H5Ocopy(...ocpypl_id...);
        ...
        ...
     }
     

\note H5Padd_merge_committed_dtype_path() will fail if the object copy property list is invalid. It will also fail if there is insufficient memory when duplicating \p path.

Returns:

\herr_t \details H5Pset_copy_object() sets properties in the object copy property list \p plist_id. When an existing object is copied, that property list will determine how the new copy is created. The following flags are available for use in an object copy property list:

#H5O_COPY_SHALLOW_HIERARCHY_FLAG	Copy only immediate members of a group Default behavior, without flag: Recursively copy all objects in and below the group.
#H5O_COPY_EXPAND_SOFT_LINK_FLAG	Expand soft links into new objects Default behavior, without flag: Copy soft links as they are.
#H5O_COPY_EXPAND_EXT_LINK_FLAG	Expand external link into new objects Default behavior, without flag: Copy external links as they are.
#H5O_COPY_EXPAND_REFERENCE_FLAG	Copy objects that are pointed to by references and update reference values in destination file Default behavior, without flag: Set reference values in destination file to zero (0)
#H5O_COPY_WITHOUT_ATTR_FLAG	Copy object without copying attributes Default behavior, without flag: Copy object with all its attributes
#H5O_COPY_MERGE_COMMITTED_DTYPE_FLAG	Use a matching committed datatype in the destination file when copying a committed datatype, a dataset with a committed datatype, or an object with an attribute of committed datatype Default behavior without flag: \li A committed datatype in the source will be copied to the destination as a committed datatype. \li If a dataset in the source uses a committed datatype or an object in the source has an attribute of a committed datatype, that committed datatype will be written to the destination as an anonymous committed datatype. If copied in a single H5Ocopy() operation, objects that share a committed datatype in the source will share an anonymous committed dataype in the destination copy. Subsequent H5Ocopy() operations, however, will be unaware of prior anonymous committed dataypes and will create new ones.

Parameters:

plist_id - [in] Object copy property list identifier

func - [in] User-defined callback function

op_data - [in] User-defined input data for the callback function

Returns:

\herr_t \details H5Pset_mcdt_search_cb() allows an application to set a callback function, \p func, that will be invoked before searching the destination file for a matching committed datatype. The default, global search process is described in H5Padd_merge_committed_dtype_path(). The callback function must conform to the #H5O_mcdt_search_cb_t prototype and will return an instruction for one of the following actions: \li Continue the search for a matching committed datatype in the destination file. \li Discontinue the search for a matching committed datatype. H5Ocopy() will then apply the default behavior of creating an anonymous committed datatype. \li Abort the copy operation and exit H5Ocopy(). \b Motivation: H5Pset_mcdt_search_cb() provides the means to define a callback function. An application can then use that callback to take an additional action before the default search of all committed datatypes in the destination file or to take an action that replaces the default search. This mechanism is intended to improve performance when the global search might take a long time. \b Example \b Usage: This example defines a callback function in the object copy property list.

 static H5O_mcdt_search_ret_t
 mcdt_search_cb(void *_udata)

 }
 

\note H5Pset_mcdt_search_cb() will fail if the object copy property list is invalid. \warning If the callback function return value causes H5Ocopy() to abort, the destination file may be left in an inconsistent or corrupted state.

\hid_t{dataspace} \details H5Ropen_region() creates a copy of the dataspace of the dataset pointed to by a region reference, \p ref_ptr, and defines a selection matching the selection pointed to by \p ref_ptr within the dataspace copy. The parameter \p rapl id is a reference access property list identifier for the reference. The access property list can be used to access external files that the reference points to (through a file access property list). The parameter \p oapl id is an object access property list identifier for the referenced object. The access property list must be of the same type as the object being referenced, that is a dataset property list in that case. Use H5Sclose() to release the dataspace identifier returned by this function when the identifier is no longer needed.

Parameters:

ref_ptr - [in] Pointer to reference to query

size - [in] Size of the \p name buffer

Returns:

Returns the length of the name if successful, otherwise, a negative value. \details H5Rget_attr_name() retrieves the attribute name for the attribute reference pointed to by \p ref_ptr. Up to size characters of the name are returned in \p name; additional characters, if any, are not returned to the user application.

Returns:

\herr_t \details Given an object reference, \p ref, H5Rget_obj_type2() returns the type of the referenced object in \p obj_type. A \Emph{reference type} is the type of reference, either an object reference or a dataset region reference.

Valid reference types, to pass in as \p ref_type, include the following: \snippet this H5R_type_t_snip If the application does not already know the object reference type, that can be determined with three preliminary calls: \li Call H5Dget_type() on the dataset containing the reference to get a datatype identifier for the dataset’s datatype. \li Using that datatype identifier, H5Tget_class() returns a datatype class.\n If the datatype class is #H5T_REFERENCE, H5Tequal() can then be used to determine whether the reference’s datatype is #H5T_STD_REF_OBJ or #H5T_STD_REF_DSETREG: - If the datatype is #H5T_STD_REF_OBJ, the reference object type is #H5R_OBJECT. - If the datatype is #H5T_STD_REF_DSETREG, the reference object type is #H5R_DATASET_REGION. When the function completes successfully, it returns one of the following valid object type values (defined in H5Opublic.h): \snippet H5Opublic.h H5O_type_t_snip

By convention, the rank of a scalar dataspace is always \p 0 (zero); think of it geometrically as a single, dimensionless point, though that point can be complex. A simple dataspace, #H5S_SIMPLE, consists of a regular array of elements. A null dataspace, #H5S_NULL, has no data elements.

Parameters:

maxdims - [in] Array specifying the maximum size of each dimension

Returns:

\hid_t{dataspace} \details H5Screate_simple() creates a new simple dataspace and opens it for access, returning a dataspace identifier. \p rank is the number of dimensions used in the dataspace. \p dims is a one-dimensional array of size rank specifying the size of each dimension of the dataset. \p maxdims is an array of the same size specifying the upper limit on the size of each dimension. Any element of \p dims can be \p 0 (zero). Note that no data can be written to a dataset if the size of any dimension of its current dataspace is \p 0. This is sometimes a useful initial state for a dataset. \p maxdims may be the null pointer, in which case the upper limit is the same as \p dims. Otherwise, no element of \p maxdims should be smaller than the corresponding element of \p dims. If an element of \p maxdims is #H5S_UNLIMITED, the maximum size of the corresponding dimension is unlimited. Any dataset with an unlimited dimension must also be chunked; see H5Pset_chunk(). Similarly, a dataset must be chunked if \p dims does not equal \p maxdims. The dataspace identifier returned from this function must be released with H5Sclose() or resource leaks will occur. \note Once a dataspace has been created, specific regions or elements in the dataspace can be selected and selections can be removed, as well. For example, H5Sselect_hyperslab() selects a region in a dataspace and H5Sselect_elements() selects array elements in a dataspace. These functions are used for subsetting. H5Sselect_none() removes all selections from a dataspace and is used in Parallel HDF5 when a process does not have or need to write data.

\ingroup H5S \brief Encodes a data space object description into a binary buffer \space_id{obj_id}

Parameters:

buf - [in,out] Buffer for the object to be encoded into; If the provided buffer is NULL, only the size of buffer needed is returned through \p nalloc.

nalloc - [in,out] The size of the allocated buffer \fapl_id{fapl}

Returns:

\herr_t \details Given the data space identifier \p obj_id, H5Sencode2() converts a data space description into binary form in a buffer. Using this binary form in the buffer, a data space object can be reconstructed with H5Sdecode() to return a new object handle (#hid_t) for this data space. A preliminary H5Sencode2() call can be made to determine the size of the buffer needed. This value is returned in \p nalloc. That value can then be assigned to \p nalloc for a second H5Sencode2() call, which will retrieve the actual encoded object. If the library determines that \p nalloc is not big enough for the object, it simply returns the size of the buffer needed through \p nalloc without encoding the provided buffer. The file access property list \p fapl_id is used to control the encoding via the \a libver_bounds property (see H5Pset_libver_bounds()). If the \a libver_bounds property is missing, H5Sencode2() proceeds as if the \a libver_bounds property were set to (#H5F_LIBVER_EARLIEST, #H5F_LIBVER_LATEST). (Functionally, H5Sencode1() is identical to H5Sencode2() with \a libver_bounds set to (#H5F_LIBVER_EARLIEST, #H5F_LIBVER_LATEST).) The types of data space that are addressed in this function are null, scalar, and simple space. For a simple data space, the information on the selection, for example, hyperslab selection, is also encoded and decoded. A complex data space has not been implemented in the library. \note Motivation: This function was introduced in HDF5-1.12 as part of the H5Sencode() format change to enable 64-bit selection encodings and a dataspace selection that is tied to a file.

\ingroup H5S \brief Retrieves a regular hyperslab selection \space_id{spaceid}

Parameters:

start - [out] Offset of the start of the regular hyperslab

stride - [out] Stride of the regular hyperslab

count - [out] Number of blocks in the regular hyperslab

block - [out] Size of a block in the regular hyperslab

Returns:

\herr_t \details H5Sget_regular_hyperslab() takes the dataspace identifier, \p spaceid, and retrieves the values of \p start, \p stride, \p count, and \p block for the regular hyperslab selection. A regular hyperslab selection is a hyperslab selection described by setting the \p offset, \p stride, \p count, and \p block parameters to the H5Sselect_hyperslab() call. If several calls to H5Sselect_hyperslab() are needed, the hyperslab selection is irregular. See H5Sselect_hyperslab() for descriptions of \p offset, \p stride, \p count, and \p block. \note If a hyperslab selection is originally regular, then becomes irregular through selection operations, and then becomes regular again, the final regular selection may be equivalent but not identical to the original regular selection.

\ingroup H5S \brief Gets the bounding box containing the current selection \space_id{spaceid}

Parameters:

start - [out] Starting coordinates of the bounding box

end - [out] Ending coordinates of the bounding box, i.e., the coordinates of the diagonally opposite corner

Returns:

\herr_t \details H5Sget_select_bounds() retrieves the coordinates of the bounding box containing the current selection and places them into user-supplied buffers. The \p start and \p end buffers must be large enough to hold the dataspace rank number of coordinates. The bounding box exactly contains the selection. I.e., if a 2-dimensional element selection is currently defined as containing the points (4,5), (6,8), and (10,7), then the bounding box will be (4, 5), (10, 8). The bounding box calculation includes the current offset of the selection within the dataspace extent. Calling this function on a \a none selection will fail.

Returns the number of element points in the current dataspace selection if successful. Otherwise returns a negative value. \details H5Sget_select_elem_npoints() returns the number of element points in the current dataspace selection, so that the element points can be retrieved with H5Sget_select_elem_pointlist().

Coincidentally, H5Sget_select_npoints() and H5Sget_select_elem_npoints() will always return the same value when an element selection is queried, but H5Sget_select_elem_npoints() does not work with other selection types.

The lengths returned are in bytes, not elements. Note that the iteration order for "all" and "hyperslab" selections is row-major (i.e. "C-ordered"), but the iteration order for "point" selections is "in order selected", unless the #H5S_SEL_ITER_GET_SEQ_LIST_SORTED flag is passed to H5Ssel_iter_create() for a point selection. \p maxseq and \p maxelmts specify the most sequences or elements possible to place into the \p off and \p len arrays. \p nseq and \p nelmts return the actual number of sequences and elements put into the arrays. Each call to H5Ssel_iter_get_seq_list() will retrieve the next set of sequences for the selection being iterated over.

\ingroup H5S \brief Selects array elements to be included in the selection for a dataspace \space_id

Parameters:

op - [in] Operator specifying how the new selection is to be combined with the existing selection for the dataspace

num_elem - [in] Number of elements to be selected

coord - [in] A pointer to a buffer containing a serialized copy of a 2-dimensional array of zero-based values specifying the coordinates of the elements in the point selection

Returns:

\herr_t \details H5Sselect_elements() selects array elements to be included in the selection for the \p space_id dataspace. This is referred to as a point selection. The number of elements selected is set in the \p num_elements parameter. The \p coord parameter is a pointer to a buffer containing a serialized 2-dimensional array of size \p num_elements by the rank of the dataspace. The array lists dataset elements in the point selection; that is, it’s a list of zero-based values specifying the coordinates in the dataset of the selected elements. The order of the element coordinates in the \p coord array specifies the order in which the array elements are iterated through when I/O is performed. Duplicate coordinate locations are not checked for. See below for examples of the mapping between the serialized contents of the buffer and the point selection array that it represents. The selection operator \p op determines how the new selection is to be combined with the previously existing selection for the dataspace. The following operators are supported:

#H5S_SELECT_SET	Replaces the existing selection with the parameters from this call. Overlapping blocks are not supported with this operator. Adds the new selection to the existing selection.
#H5S_SELECT_APPEND	Adds the new selection following the last element of the existing selection.
#H5S_SELECT_PREPEND	Adds the new selection preceding the first element of the existing selection.

Mapping the serialized \p coord buffer to a 2-dimensional point selection array: To illustrate the construction of the contents of the \p coord buffer, consider two simple examples: a selection of 5 points in a 1-dimensional array and a selection of 3 points in a 4-dimensional array. In the 1D case, we will be selecting five points and a 1D dataspace has rank 1, so the selection will be described in a 5-by-1 array. To select the 1st, 14th, 17th, 23rd and 8th elements of the dataset, the selection array would be as follows (remembering that point coordinates are zero-based): \n 0 \n 13 \n 16 \n 22 \n 7 This point selection array will be serialized in the \p coord buffer as: \n 0 13 16 22 7 In the 4D case, we will be selecting three points and a 4D dataspace has rank 4, so the selection will be described in a 3-by-4 array. To select the points (1,1,1,1), (14,6,12,18), and (8,22,30,22), the point selection array would be as follows: \n 0 0 0 0 \n 13 5 11 17 \n 7 21 29 21 This point selection array will be serialized in the \p coord buffer as: \n 0 0 0 0 13 5 11 17 7 21 29 21

\ingroup H5S \brief Selects a hyperslab region to add to the current selected region \space_id

Parameters:

op - [in] Operation to perform on current selection

start - [in] Offset of start of hyperslab

stride - [in] Hyperslab stride

count - [in] Number of blocks included in hyperslab

block - [in] Size of block in hyperslab

Returns:

\herr_t \details H5Sselect_hyperslab() selects a hyperslab region to add to the current selected region for the dataspace specified by \p space_id. The \p start, \p stride, \p count, and \p block arrays must be the same size as the rank of the dataspace. For example, if the dataspace is 4-dimensional, each of these parameters must be a 1-dimensional array of size 4. The selection operator \p op determines how the new selection is to be combined with the already existing selection for the dataspace. The following operators are supported:

#H5S_SELECT_SET	Replaces the existing selection with the parameters from this call. Overlapping blocks are not supported with this operator.
#H5S_SELECT_OR	Adds the new selection to the existing selection. (Binary OR)
#H5S_SELECT_AND	Retains only the overlapping portions of the new selection and the existing selection. (Binary AND)
#H5S_SELECT_XOR	Retains only the elements that are members of the new selection or the existing selection, excluding elements that are members of both selections. (Binary exclusive-OR, XOR)
#H5S_SELECT_NOTB	Retains only elements of the existing selection that are not in the new selection.
#H5S_SELECT_NOTA	Retains only elements of the new selection that are not in the existing selection.

The \p start array specifies the offset of the starting element of the specified hyperslab. The \p stride array chooses array locations from the dataspace with each value in the \p stride array determining how many elements to move in each dimension. Setting a value in the \p stride array to \p 1 moves to each element in that dimension of the dataspace; setting a value of \p 2 in allocation in the \p stride array moves to every other element in that dimension of the dataspace. In other words, the \p stride determines the number of elements to move from the \p start location in each dimension. Stride values of \p 0 are not allowed. If the \p stride parameter is NULL, a contiguous hyperslab is selected (as if each value in the \p stride array were set to \p 1). The \p count array determines how many blocks to select from the dataspace, in each dimension. The \p block array determines the size of the element block selected from the dataspace. If the \p block parameter is set to NULL, the block size defaults to a single element in each dimension (as if each value in the \p block array were set to \p 1). For example, consider a 2-dimensional dataspace with hyperslab selection settings as follows: the \p start offset is specified as [1,1], \p stride is [4,4], \p count is [3,7], and \p block is [2,2]. In C, these settings will specify a hyperslab consisting of 21 2x2 blocks of array elements starting with location (1,1) with the selected blocks at locations (1,1), (5,1), (9,1), (1,5), (5,5), etc.; in Fortran, they will specify a hyperslab consisting of 21 2x2 blocks of array elements starting with location (2,2) with the selected blocks at locations (2,2), (6,2), (10,2), (2,6), (6,6), etc. Regions selected with this function call default to C order iteration when I/O is performed.

Returns:

\herr_t \details H5Pset_fapl_core() modifies the file access property list to use the #H5FD_CORE driver. The #H5FD_CORE driver enables an application to work with a file in memory, speeding reads and writes as no disk access is made. File contents are stored only in memory until the file is closed. The \p backing_store parameter determines whether file contents are ever written to disk. \p increment specifies the increment by which allocated memory is to be increased each time more memory is required. While using H5Fcreate() to create a core file, if the \p backing_store is set to 1 (TRUE), the file contents are flushed to a file with the same name as this core file when the file is closed or access to the file is terminated in memory. The application is allowed to open an existing file with #H5FD_CORE driver. While using H5Fopen() to open an existing file, if the \p backing_store is set to 1 (TRUE) and the \c flags for H5Fopen() is set to #H5F_ACC_RDWR, any change to the file contents are saved to the file when the file is closed. If \p backing_store is set to 0 (FALSE) and the \c flags for H5Fopen() is set to #H5F_ACC_RDWR, any change to the file contents will be lost when the file is closed. If the flags for H5Fopen() is set to #H5F_ACC_RDONLY, no change to the file is allowed either in memory or on file. \note Currently this driver cannot create or open family or multi files.

\ingroup FAPL \brief Sets up the logging virtual file driver (#H5FD_LOG) for use \fapl_id

Parameters:

logfile - [in] Name of the log file

flags - [in] Flags specifying the types of logging activity

buf_size - [in] The size of the logging buffers, in bytes (see description)

Returns:

\herr_t \details H5Pset_fapl_log() modifies the file access property list to use the logging driver, #H5FD_LOG. The logging virtual file driver (VFD) is a clone of the standard SEC2 (#H5FD_SEC2) driver with additional facilities for logging VFD metrics and activity to a file. \p logfile is the name of the file in which the logging entries are to be recorded. The actions to be logged are specified in the parameter \p flags using the pre-defined constants described in the following table. Multiple flags can be set through the use of a logical \c OR contained in parentheses. For example, logging read and write locations would be specified as \Code{(H5FD_LOG_LOC_READ|H5FD_LOG_LOC_WRITE)}.

Table1: Logging Flags

#H5FD_LOG_LOC_READ	Track the location and length of every read, write, or seek operation.
#H5FD_LOG_LOC_WRITE
#H5FD_LOG_LOC_SEEK
#H5FD_LOG_LOC_IO	Track all I/O locations and lengths. The logical equivalent of the following: \Code{(#H5FD_LOG_LOC_READ | #H5FD_LOG_LOC_WRITE | #H5FD_LOG_LOC_SEEK)}
#H5FD_LOG_FILE_READ	Track the number of times each byte is read or written.
#H5FD_LOG_FILE_WRITE
#H5FD_LOG_FILE_IO	Track the number of times each byte is read and written. The logical equivalent of the following: \Code{(#H5FD_LOG_FILE_READ | #H5FD_LOG_FILE_WRITE)}
#H5FD_LOG_FLAVOR	Track the type, or flavor, of information stored at each byte.
#H5FD_LOG_NUM_READ	Track the total number of read, write, seek, or truncate operations that occur.
#H5FD_LOG_NUM_WRITE
#H5FD_LOG_NUM_SEEK
#H5FD_LOG_NUM_TRUNCATE
#H5FD_LOG_NUM_IO	Track the total number of all types of I/O operations. The logical equivalent of the following: \Code{(#H5FD_LOG_NUM_READ | #H5FD_LOG_NUM_WRITE | #H5FD_LOG_NUM_SEEK | #H5FD_LOG_NUM_TRUNCATE)}
#H5FD_LOG_TIME_OPEN	Track the time spent in open, stat, read, write, seek, or close operations.
#H5FD_LOG_TIME_STAT
#H5FD_LOG_TIME_READ
#H5FD_LOG_TIME_WRITE
#H5FD_LOG_TIME_SEEK
#H5FD_LOG_TIME_CLOSE
#H5FD_LOG_TIME_IO	Track the time spent in each of the above operations. The logical equivalent of the following: \Code{(#H5FD_LOG_TIME_OPEN | #H5FD_LOG_TIME_STAT | #H5FD_LOG_TIME_READ | #H5FD_LOG_TIME_WRITE | #H5FD_LOG_TIME_SEEK | #H5FD_LOG_TIME_CLOSE)}
#H5FD_LOG_ALLOC	Track the allocation of space in the file.
#H5FD_LOG_ALL	Track everything. The logical equivalent of the following: \Code{(#H5FD_LOG_ALLOC | #H5FD_LOG_TIME_IO | #H5FD_LOG_NUM_IO | #H5FD_LOG_FLAVOR | #H5FD_LOG_FILE_IO | #H5FD_LOG_LOC_IO)}

The logging driver can track the number of times each byte in the file is read from or written to (using #H5FD_LOG_FILE_READ and #H5FD_LOG_FILE_WRITE) and what kind of data is at that location (e.g., metadata, raw data; using #H5FD_LOG_FLAVOR). This information is tracked in internal buffers of size buf_size, which must be at least the maximum size in bytes of the file to be logged while the log driver is in use.\n One buffer of size buf_size will be created for each of #H5FD_LOG_FILE_READ, #H5FD_LOG_FILE_WRITE and #H5FD_LOG_FLAVOR when those flags are set; these buffers will not grow as the file increases in size. \par Output: This section describes the logging driver (LOG VFD) output.\n The table, immediately below, describes output of the various logging driver flags and function calls. A list of valid flavor values, describing the type of data stored, follows the table.

\ingroup FAPL \brief Sets up use of the multi-file driver \fapl_id

Parameters:

memb_map - [in] Maps memory usage types to other memory usage types

memb_fapl - [in] Property list for each memory usage type

memb_name - [in] Name generator for names of member files

memb_addr - [in] The offsets within the virtual address space, from 0 (zero) to #HADDR_MAX, at which each type of data storage begins

relax - [in] Allows read-only access to incomplete file sets when \c TRUE

Returns:

\herr_t \details H5Pset_fapl_multi() sets the file access property list \p fapl_id to use the multi-file driver. The multi-file driver enables different types of HDF5 data and metadata to be written to separate files. These files are viewed by the HDF5 library and the application as a single virtual HDF5 file with a single HDF5 file address space. The types of data that can be broken out into separate files include raw data, the superblock, B-tree data, global heap data, local heap data, and object headers. At the programmer's discretion, two or more types of data can be written to the same file while other types of data are written to separate files. The array \p memb_map maps memory usage types to other memory usage types and is the mechanism that allows the caller to specify how many files are created. The array contains #H5FD_MEM_NTYPES entries, which are either the value #H5FD_MEM_DEFAULT or a memory usage type. The number of unique values determines the number of files that are opened. The array \p memb_fapl contains a property list for each memory usage type that will be associated with a file. The array \p memb_name should be a name generator (a \Code{printf}-style format with a \Code{%s} which will be replaced with the name passed to H5FDopen(), usually from H5Fcreate() or H5Fopen()). The array \p memb_addr specifies the offsets within the virtual address space, from 0 (zero) to #HADDR_MAX, at which each type of data storage begins. If \p relax is set to 1 (TRUE), then opening an existing file for read-only access will not fail if some file members are missing. This allows a file to be accessed in a limited sense if just the meta data is available. Default values for each of the optional arguments are as follows:

\p memb_map	The default member map contains the value #H5FD_MEM_DEFAULT for each element.
\p memb_fapl	The default value is #H5P_DEFAULT for each element.
\p memb_name	The default string is \Code{%s-X.h5} where \c X is one of the following letters: - \c s for #H5FD_MEM_SUPER - \c b for #H5FD_MEM_BTREE - \c r for #H5FD_MEM_DRAW - \c g for #H5FD_MEM_GHEAP - \c l for #H5FD_MEM_LHEAP - \c o for #H5FD_MEM_OHDR
\p memb_addr	The default setting is that the address space is equally divided among all of the elements: - #H5FD_MEM_SUPER \Code{-> 0 * (HADDR_MAX/6)} - #H5FD_MEM_BTREE \Code{-> 1 * (HADDR_MAX/6)} - #H5FD_MEM_DRAW \Code{-> 2 * (HADDR_MAX/6)} - #H5FD_MEM_GHEAP \Code{-> 3 * (HADDR_MAX/6)} - #H5FD_MEM_LHEAP \Code{-> 4 * (HADDR_MAX/6)} - #H5FD_MEM_OHDR \Code{-> 5 * (HADDR_MAX/6)}

\par Example: The following code sample sets up a multi-file access property list that partitions data into meta and raw files, each being one-half of the address:\n

 H5FD_mem_t mt, memb_map[H5FD_MEM_NTYPES];
 hid_t memb_fapl[H5FD_MEM_NTYPES];
 const char *memb[H5FD_MEM_NTYPES];
 haddr_t memb_addr[H5FD_MEM_NTYPES];

 // The mapping...
 for (mt=0; mt<H5FD_MEM_NTYPES; mt++) {
   memb_map[mt] = H5FD_MEM_SUPER;
 }
 memb_map[H5FD_MEM_DRAW] = H5FD_MEM_DRAW;

 // Member information
 memb_fapl[H5FD_MEM_SUPER] = H5P_DEFAULT;
 memb_name[H5FD_MEM_SUPER] = "%s.meta";
 memb_addr[H5FD_MEM_SUPER] = 0;

 memb_fapl[H5FD_MEM_DRAW] = H5P_DEFAULT;
 memb_name[H5FD_MEM_DRAW] = "%s.raw";
 memb_addr[H5FD_MEM_DRAW] = HADDR_MAX/2;

\ingroup FAPL \brief Emulates the old split file driver \fapl_id{fapl}

Parameters:

Returns:

\herr_t \details H5Pset_fapl_split() is a compatibility function that enables the multi-file driver to emulate the split driver from HDF5 Releases 1.0 and 1.2. The split file driver stored metadata and raw data in separate files but provided no mechanism for separating types of metadata. \p fapl is a file access property list identifier. \p meta_ext is the filename extension for the metadata file. The extension is appended to the name passed to H5FDopen(), usually from H5Fcreate() or H5Fopen(), to form the name of the metadata file. If the string \Code{%s} is used in the extension, it works like the name generator as in H5Pset_fapl_multi(). \p meta_plist_id is the file access property list identifier for the metadata file. \p raw_ext is the filename extension for the raw data file. The extension is appended to the name passed to H5FDopen(), usually from H5Fcreate() or H5Fopen(), to form the name of the raw data file. If the string \Code{%s} is used in the extension, it works like the name generator as in H5Pset_fapl_multi(). \p raw_plist_id is the file access property list identifier for the raw data file. If a user wishes to check to see whether this driver is in use, the user must call H5Pget_driver() and compare the returned value to the string #H5FD_MULTI. A positive match will confirm that the multi driver is in use; HDF5 provides no mechanism to determine whether it was called as the special case invoked by H5Pset_fapl_split(). \par Example:

 // Example 1: Both metadata and raw data files are in the same
 //            directory. Use Station1-m.h5 and Station1-r.h5 as
 //            the metadata and raw data files.
 hid_t fapl, fid;
 fapl = H5Pcreate(H5P_FILE_ACCESS);
 H5Pset_fapl_split(fapl, "-m.h5", H5P_DEFAULT, "-r.h5", H5P_DEFAULT);
 fid=H5Fcreate("Station1",H5F_ACC_TRUNC,H5P_DEFAULT,fapl);

 // Example 2: metadata and raw data files are in different
 //            directories.  Use PointA-m.h5 and /pfs/PointA-r.h5 as
 //            the metadata and raw data files.
 hid_t fapl, fid;
 fapl = H5Pcreate(H5P_FILE_ACCESS);
 H5Pset_fapl_split(fapl, "-m.h5", H5P_DEFAULT, "/pfs/%s-r.h5", H5P_DEFAULT);
 fid=H5Fcreate("PointA",H5F_ACC_TRUNC,H5P_DEFAULT,fapl);

Parameters:

dset_id - [in] Dataset identifier

dxpl_id - [in] Dataset transfer property list identifier

axis - [in] Dataset Dimension (0-based) for the append

extension - [in] Number of elements to append for the axis-th dimension

memtype - [in] The memory datatype identifier

buf - [in] Buffer with data for the append

Returns:

\herr_t \details The H5DOappend() routine extends a dataset by \p extension number of elements along a dimension specified by a dimension \p axis and writes \p buf of elements to the dataset. Dimension \p axis is 0-based. Elements’ type is described by \p memtype. This routine combines calling H5Dset_extent(), H5Sselect_hyperslab(), and H5Dwrite() into a single routine that simplifies application development for the common case of appending elements to an existing dataset. For a multi-dimensional dataset, appending to one dimension will write a contiguous hyperslab over the other dimensions. For example, if a 3-D dataset has dimension sizes (3, 5, 8), extending the 0th dimension (currently of size 3) by 3 will append 3*5*8 = 120 elements (which must be pointed to by the \p buffer parameter) to the dataset, making its final dimension sizes (6, 5, 8). If a dataset has more than one unlimited dimension, any of those dimensions may be appended to, although only along one dimension per call to H5DOappend().

(The value passed in with the parameter \p size must be one greater than size in bytes of the actual name in order to accommodate the null terminator; if \p size is set to the exact size of the name, the last byte passed back will contain the null terminator and the last character will be missing from the name passed back to the calling application.)

-------------------------------------------------------------------------- \ingroup H5DS \brief Iterates the operation visitor through the scales attached to dimension \p dim.

Parameters:

did - [in] The dataset

dim - [in] The dimension of dataset \p did

idx - [in,out] Input the index to start iterating, output the next index to visit. If NULL, start at the first position.

visitor - [in] The visitor function

visitor_data - [in] Arbitrary data to pass to the visitor function

Returns:

Returns the return value of the last operator if it was non-zero, or zero if all scales were processed. \details H5DSiterate_scales() iterates over the scales attached to dimension \p dim of dataset \p did. For each scale in the list, the \p visitor_data and some additional information, specified below, are passed to the \p visitor function. The iteration begins with the \p idx object in the group and the next element to be processed by the operator is returned in \p idx. If \p idx is NULL, then the iterator starts at the first group member; since no stopping point is returned in this case, the iterator cannot be restarted if one of the calls to its operator returns non-zero. The prototype for \ref H5DS_iterate_t is: \snippet this H5DS_iterate_t_snip The operation receives the Dimension Scale dataset identifier, \p scale, and the pointer to the operator data passed in to H5DSiterate_scales(), \p visitor_data. The return values from an operator are: - Zero causes the iterator to continue, returning zero when all group members have been processed. - Positive causes the iterator to immediately return that positive value, indicating short-circuit success. The iterator can be restarted at the next group member. - Negative causes the iterator to immediately return that value, indicating failure. The iterator can be restarted at the next group member. H5DSiterate_scales() assumes that the scales of the dimension identified by \p dim remain unchanged through the iteration. If the membership changes during the iteration, the function's behavior is undefined.

------------------------------------------------------------------------- \ingroup H5LT \brief Creates a text description of an HDF5 datatype.

Parameters:

str - [out] Buffer for the text description of the datatype

lang_type - [in] The language used to describe the datatype. The currently supported language is #H5LT_DDL.

len - [out] The size of buffer needed to store the text description

Returns:

\herr_t \details Given an HDF5 datatype identifier, this function creates a description of this datatype in \p lang_type language format. A preliminary H5LTdtype_to_text() call can be made to determine the size of the buffer needed with a NULL passed in for \p str. This value is returned as \p len. That value can then be assigned to len for a second H5Ttype_to_text() call, which will retrieve the actual text description for the datatype. If \p len is not big enough for the description, the text description will be truncated to fit in the buffer. Currently only DDL (#H5LT_DDL) is supported for \p lang_type.

Parameters:

buf_ptr - [in] A pointer to the supplied initial image

buf_size - [in] Size of the supplied buffer

flags - [in] Flags specifying whether to open the image read-only or read/write, whether HDF5 is to take control of the buffer, and instruction regarding releasing the buffer.

Returns:

Returns a file identifier if successful; otherwise returns a negative value. \warning \Bold{Failure Modes:} \warning H5LTopen_file_image() will fail if either \p buf_ptr is NULL or \p buf_size equals 0 (zero). \details H5LTopen_file_image() opens the HDF5 file image that is located in system memory at the address indicated by \p buf_ptr of size \p buf_size. H5LTopen_file_image() opens a file image with the Core driver, #H5FD_CORE. A value of NULL for \p buf_ptr is invalid and will cause the function to fail. A value of 0 for \p buf_size is invalid and will cause the function to fail. The flags passed in \p flags specify whether to open the image read-only or read/write, whether HDF5 is to take control of the buffer, and instruction regarding releasing the buffer. Valid values are: - #H5LT_FILE_IMAGE_OPEN_RW - Specifies opening the file image in read/write mode. - Default without this flag: File image will be opened read-only. - #H5LT_FILE_IMAGE_DONT_COPY - Specifies to not copy the provided file image buffer; the buffer will be used directly. HDF5 will release the file image when finished. - Default without this flag: Copy the file image buffer and open the copied file image. - #H5LT_FILE_IMAGE_DONT_RELEASE - Specifies that HDF5 is not to release the buffer when the file opened with H5LTopen_file_image() is closed; releasing the buffer will be left to the application. - Default without this flag: HDF5 will automatically release the file image buffer after the file image is closed. This flag is valid only when used with #H5LT_FILE_IMAGE_DONT_COPY. \note **Motivation:** \note H5LTopen_file_image() and other elements of HDF5 are used to load an image of an HDF5 file into system memory and open that image as a regular HDF5 file. An application can then use the file without the overhead of disk I/O. \note **Recommended Reading:** \note This function is part of the file image operations feature set. It is highly recommended to study the guide HDF5 File Image Operations before using this feature set.\n See the “See Also” section below for links to other elements of HDF5 file image operations. \todo There is no "See Also" section???

buffer - [in] Buffer with data to be written to the dataset

Returns:

\herr_t \details H5IMmake_image_8bit() creates and writes a dataset named \p dset_name attached to the file or group specified by the identifier \p loc_id. Attributes conforming to the HDF5 Image and Palette specification for an indexed image are attached to the dataset, thus identifying it as an image. The image data is of the type #H5T_NATIVE_UCHAR. An indexed image is an image in which each each pixel information storage is an index to a table palette.

-------------------------------------------------------------------------- \ingroup H5IM \brief Creates and writes a true color image. \fg_loc_id

Parameters:

dset_name - [in] The name of the dataset to create

width - [in] The width of the image

height - [in] The height of the image

interlace - [in] String defining the interlace mode

buffer - [in] Buffer with data to be written to the dataset

Returns:

\herr_t \details H5IMmake_image_24bit() creates and writes a dataset named \p dset_name attached to the file or group specified by the identifier \p loc_id. This function defines a true color image conforming to the HDF5 Image and Palette specification. The function assumes that the image data is of the type #H5T_NATIVE_UCHAR. A true color image is an image where the pixel storage contains several color planes. In a 24 bit RGB color model, these planes are red, green and blue. In a true color image the stream of bytes can be stored in several different ways, thus defining the interlace (or interleaving) mode. The 2 most used types of interlace mode are interlace by pixel and interlace by plane. In the 24 bit RGB color model example, interlace by plane means all the red components for the entire dataset are stored first, followed by all the green components, and then by all the blue components. Interlace by pixel in this example means that for each pixel the sequence red, green, blue is defined. In this function, the interlace mode is defined in the parameter \p interlace, a string that can have the values INTERLACE_PIXEL or INTERLACE_PLANE.

-------------------------------------------------------------------------- \ingroup H5PT \brief Creates a packet table to store fixed-length or variable-length packets. \fg_loc_id

Parameters:

dset_name - [in] The name of the packet table to create

dtype_id - [in] The datatype of the packet

chunk_size - [in] The size in number of table entries per chunk

plist_id - [in] Identifier of the property list. Can be used to specify the compression of the packet table.

Returns:

Returns an identifier for the new packet table or #H5I_INVALID_HID on error. \details The H5PTcreate() creates and opens a packet table named \p dset_name attached to the object specified by the identifier \p loc_id. The created packet table should be closed with H5PTclose(), eventually. The datatype, \p dtype_id, may specify any datatype, including variable-length data. If \p dtype_id specifies a compound datatype, one or more fields in that compound type may be variable-length. \p chunk_size is the size in number of table entries per chunk. Packet table datasets use HDF5 chunked storage to allow them to grow. This value allows the user to set the size of a chunk. The chunk size affects performance.

Parameters:

prev_dims - [in] The previous dimension size of the dataset

cur_dims - [in] The current dimension sizes of the dataset

fields - [in] A string containing a comma-separated list of fields for a compound datatype

buf - [out] Buffer for storing data retrieved from the dataset

Returns:

\herr_t \details H5LDget_dset_dims() retrieves selected data of the dataset \p did and stores the data in the parameter \p buf. The difference between the parameters \p prev_dims and \p cur_dims indicates the dimension sizes of the data to be selected from the dataset. Note that \p cur_dims must have at least one dimension whose size is greater than the corresponding dimension in \p prev_dims. Users can determine the size of buf by multiplying the datatype size of the dataset by the number of selected elements. If the parameter \p fields is NULL, this routine returns data for the selected elements of the dataset. If \p fields is not NULL and the dataset has a compound datatype, \p fields is a string containing a comma-separated list of fields. Each name in \p fields specifies a field in the compound datatype, and this routine returns data of the selected fields for the dataset's selected elements. Note that ’,’ is the separator for the fields of a compound datatype while ’.’ is the separator for a nested field.

\ingroup H5I \brief Registers a "future" object under a type and returns an ID for it

Parameters:

type - [in] The identifier of the type of the new ID

object - [in] Pointer to "future" object for which a new ID is created

realize_cb - [in] Function pointer to realize a future object

discard_cb - [in] Function pointer to destroy a future object

Returns:

\hid_t{object} \details H5Iregister_future() creates and returns a new ID for a "future" object. Future objects are a special kind of object and represent a placeholder for an object that has not yet been created or opened. The \p realize_cb will be invoked by the HDF5 library to 'realize' the future object as an actual object. A call to H5Iobject_verify() will invoke the \p realize_cb callback and if it successfully returns, will return the actual object, not the future object. \details The \p type parameter is the identifier for the ID type to which this new future ID will belong. This identifier may have been created by a call to H5Iregister_type() or may be one of the HDF5 pre-defined ID classes (e.g. H5I_FILE, H5I_GROUP, H5I_DATASPACE, etc). \details The \p object parameter is a pointer to the memory which the new ID will be a reference to. This pointer will be stored by the library, but will not be returned to a call to H5Iobject_verify() until the \p realize_cb callback has returned the actual pointer for the object. A NULL value for \p object is allowed. \details The \p realize_cb parameter is a function pointer that will be invoked by the HDF5 library to convert a future object into an actual object. The \p realize_cb function may be invoked by H5Iobject_verify() to return the actual object for a user-defined ID class (i.e. an ID class registered with H5Iregister_type()) or internally by the HDF5 library in order to use or get information from an HDF5 pre-defined ID type. For example, the \p realize_cb for a future dataspace object will be called during the process of returning information from H5Sget_simple_extent_dims(). Note that although the \p realize_cb routine returns an ID (as a parameter) for the actual object, the HDF5 library will swap the actual object in that ID for the future object in the future ID. This ensures that the ID value for the object doesn't change for the user when the object is realized. Note that the \p realize_cb callback could receive a NULL value for a future object pointer, if one was used when H5Iregister_future() was initially called. This is permitted as a means of allowing the \p realize_cb to act as a generator of new objects, without requiring creation of unnecessary future objects. It is an error to pass NULL for \p realize_cb. \details The \p discard_cb parameter is a function pointer that will be invoked by the HDF5 library to destroy a future object. This callback will always be invoked for _every_ future object, whether the \p realize_cb is invoked on it or not. It's possible that the \p discard_cb is invoked on a future object without the \p realize_cb being invoked, e.g. when a future ID is closed without requiring the future object to be realized into an actual one. Note that the \p discard_cb callback could receive a NULL value for a future object pointer, if one was used when H5Iregister_future() was initially called. It is an error to pass NULL for \p discard_cb. \note The H5Iregister_future() function is primarily targeted at VOL connector authors and is _not_ designed for general-purpose application use.

H5Lregister

\ingroup H5LA \brief Registers a user-defined link class or changes behavior of an existing class

Parameters:

cls - [in] Pointer to a buffer containing the struct describing the user-defined link class

Returns:

\herr_t \details H5Lregister() registers a class of user-defined links, or changes the behavior of an existing class. \p cls is a pointer to a buffer containing a copy of the H5L_class_t struct. This struct is defined in H5Lpublic.h as follows: \snippet this H5L_class_t_snip The class definition passed with \p cls must include at least the following: \li An H5L_class_t version (which should be #H5L_LINK_CLASS_T_VERS) \li A link class identifier, \c class_id \li A traversal function, \c trav_func Remaining \c struct members are optional and may be passed as NULL. The link class passed in \c class_id must be in the user-definable range between #H5L_TYPE_UD_MIN and #H5L_TYPE_UD_MAX (see the table below) and will override any existing link class with that identifier. As distributed, valid values of \c class_id used in HDF5 include the following (defined in H5Lpublic.h): \link_types The hard and soft link class identifiers cannot be modified or reassigned, but the external link class is implemented as an example in the user-definable link class identifier range. H5Lregister() is used to register additional link classes. It could also be used to modify the behavior of the external link class, though that is not recommended. The following table summarizes existing link types and values and the reserved and user-definable link class identifier value ranges.

Link class identifier or Value range	Description	Link class or label
0 to 63	Reserved range
64 to 255	User-definable range
64	Minimum user-defined value	#H5L_TYPE_UD_MIN
64	External link	#H5L_TYPE_EXTERNAL
255	Maximum user-defined value	#H5L_TYPE_UD_MAX
255	Maximum value	#H5L_TYPE_MAX
-1	Error	#H5L_TYPE_ERROR

Note that HDF5 internally registers user-defined link classes only by the numeric value of the link class identifier. An application, on the other hand, will generally use a name for a user-defined class, if for no other purpose than as a variable name. Assume, for example, that a complex link type is registered with the link class identifier 73 and that the code includes the following assignment:

          H5L_TYPE_COMPLEX_A = 73
          

The application can refer to the link class with a term, \c H5L_TYPE_COMPLEX_A, that conveys meaning to a human reviewing the code, while HDF5 recognizes it by the more cryptic numeric identifier, 73. \attention Important details and considerations include the following: \li If you plan to distribute files or software with a user-defined link class, please contact the Help Desk at The HDF Group to help prevent collisions between \c class_id values. See below. \li As distributed with HDF5, the external link class is implemented as an example of a user-defined link class with #H5L_TYPE_EXTERNAL equal to #H5L_TYPE_UD_MIN. \c class_id in the H5L_class_t \c struct must not equal #H5L_TYPE_UD_MIN unless you intend to overwrite or modify the behavior of external links. \li H5Lregister() can be used only with link class identifiers in the user-definable range (see table above). \li The hard and soft links defined by the HDF5 library, #H5L_TYPE_HARD and #H5L_TYPE_SOFT, reside in the reserved range below #H5L_TYPE_UD_MIN and cannot be redefined or modified. \li H5Lis_registered() can be used to determine whether a desired link class identifier is available. \Emph{Note that this function will tell you only whether the link class identifier has been registered with the installed copy of HDF5; it cannot tell you whether the link class has been registered with The HDF Group.} \li #H5L_TYPE_MAX is the maximum allowed value for a link type identifier. \li #H5L_TYPE_UD_MIN equals #H5L_TYPE_EXTERNAL. \li #H5L_TYPE_UD_MAX equals #H5L_TYPE_MAX. \li #H5L_TYPE_ERROR indicates that an error has occurred. \note \Bold{Registration with The HDF Group:}\n There are sometimes reasons to take a broader approach to registering a user-defined link class than just invoking H5Lregister(). For example: \li A user-defined link class is intended for use across an organization, among collaborators, or across a community of users. \li An application or library overlying HDF5 invokes a user-defined link class that must be shipped with the software. \li Files are distributed that make use of a user-defined link class. \li Or simply, a specific user-defined link class is thought to be widely useful. In such cases, you are encouraged to register that link class with The HDF Group's Helpdesk. The HDF Group maintains a registry of known user-defined link classes and tracks the selected link class identifiers. This registry is intended to reduce the risk of collisions between \c class_id values and to help coordinate the use of specialized link classes.

Returns:

\herr_t \details H5Tregister() registers a hard or soft conversion function for a datatype conversion path. The parameter \p pers indicates whether a conversion function is hard (#H5T_PERS_HARD) or soft (#H5T_PERS_SOFT). User-defined functions employing compiler casting are designated as \Emph{hard}; other user-defined conversion functions registered with the HDF5 library (with H5Tregister() ) are designated as \Emph{soft}. The HDF5 library also has its own hard and soft conversion functions. A conversion path can have only one hard function. When type is #H5T_PERS_HARD, \p func replaces any previous hard function. When type is #H5T_PERS_SOFT, H5Tregister() adds the function to the end of the master soft list and replaces the soft function in all applicable existing conversion paths. Soft functions are used when determining which conversion function is appropriate for this path. The \p name is used only for debugging and should be a short identifier for the function. The path is specified by the source and destination datatypes \p src_id and \p dst_id. For soft conversion functions, only the class of these types is important.

\ingroup H5Z \brief Registers a new filter with the HDF5 library

Parameters:

cls - [in] A pointer to a buffer for the struct containing the filter-definition

Returns:

\herr_t \details H5Zregister() registers a new filter with the HDF5 library. \details Making a new filter available to an application is a two-step process. The first step is to write the three filter callback functions described below: \c can_apply, \c set_local, and \c filter. This call to H5Zregister(), registering the filter with the library, is the second step. The can_apply and set_local fields can be set to NULL if they are not required for the filter being registered. H5Zregister() accepts a single parameter, a pointer to a buffer for the \p cls data structure. That data structure must conform to one of the following definitions: \snippet this H5Z_class1_t_snip or \snippet this H5Z_class2_t_snip \c version is a library-defined value reporting the version number of the #H5Z_class_t struct. This currently must be set to #H5Z_CLASS_T_VERS. \c id is the identifier for the new filter. This is a user-defined value between #H5Z_FILTER_RESERVED and #H5Z_FILTER_MAX. These values are defined in the HDF5 source file H5Zpublic.h, but the symbols #H5Z_FILTER_RESERVED and #H5Z_FILTER_MAX should always be used instead of the literal values. \c encoder_present is a library-defined value indicating whether the filter’s encoding capability is available to the application. \c decoder_present is a library-defined value indicating whether the filter’s encoding capability is available to the application. \c name is a descriptive comment used for debugging, may contain a descriptive name for the filter, and may be the null pointer. \c can_apply, described in detail below, is a user-defined callback function that determines whether the combination of the dataset creation property list values, the datatype, and the dataspace represent a valid combination to apply this filter to. \c set_local, described in detail below, is a user-defined callback function that sets any parameters that are specific to this dataset, based on the combination of the dataset creation property list values, the datatype, and the dataspace. \c filter, described in detail below, is a user-defined callback function which performs the action of the filter. The statistics associated with a filter are not reset by this function; they accumulate over the life of the library. #H5Z_class_t is a macro that maps to either H5Z_class1_t or H5Z_class2_t, depending on the needs of the application. To affect only this macro, H5Z_class_t_vers may be defined as either 1 or 2. Otherwise, it will behave in the same manner as other API compatibility macros. See API Compatibility Macros in HDF5 for more information. H5Z_class1_t matches the #H5Z_class_t structure that is used in the 1.6.x versions of the HDF5 library. H5Zregister() will automatically detect which structure type has been passed in, regardless of the mapping of the #H5Z_class_t macro. However, the application must make sure that the fields are filled in according to the correct structure definition if the macro is used to declare the structure. \Bold{The callback functions:}\n Before H5Zregister() can link a filter into an application, three callback functions must be defined as described in the HDF5 library header file H5Zpublic.h. When a filter is applied to the fractal heap for a group (e.g., when compressing group metadata) and if they can apply and set local callback functions that have been defined for that filter, HDF5 passes the value -1 for all parameters for those callback functions. This is done to ensure that the filter will not be applied to groups if it relies on these parameters, as they are not applicable to group fractal heaps; to operate on group fractal heaps, a filter must be capable of operating on an opaque block of binary data. The \Emph{can-apply} callback function must return a positive value for a valid combination, zero for an invalid combination, and a negative value for an error. \snippet this H5Z_can_apply_func_t_snip Before a dataset is created, the \Emph{can apply} callbacks for any filters used in the dataset creation property list are called with the dataset's dataset creation property list, \c dcpl_id, the dataset's datatype, \p type_id, and a dataspace describing a chunk, \p space_id, (for chunked dataset storage). This callback must determine whether the combination of the dataset creation property list settings, the datatype, and the dataspace represent a valid combination to which to apply this filter. For example, an invalid combination may involve the filter not operating correctly on certain datatypes, on certain datatype sizes, or on certain sizes of the chunk dataspace. If this filter is enabled through H5Pset_filter() as optional and the can apply function returns 0, the library will skip the filter in the filter pipeline. This callback can be the NULL pointer, in which case the library will assume that the filter can be applied to a dataset with any combination of dataset creation property list values, datatypes, and dataspaces. The \Emph{set local} callback function is defined as follows: \snippet this H5Z_set_local_func_t_snip After the can apply callbacks are checked for a new dataset, the \Emph{set local} callback functions for any filters used in the dataset creation property list are called. These callbacks receive \c dcpl_id, the dataset's private copy of the dataset creation property list passed into H5Dcreate() (i.e. not the actual property list passed into H5Dcreate()); \c type_id, the datatype identifier passed into H5Dcreate(), which is not copied and should not be modified; and \c space_id, a dataspace describing the chunk (for chunked dataset storage), which should also not be modified. The set local callback must set any filter parameters that are specific to this dataset, based on the combination of the dataset creation property list values, the datatype, and the dataspace. For example, some filters perform different actions based on different datatypes, datatype sizes, numbers of dimensions, or dataspace sizes. The \Emph{set local} callback may be the NULL pointer, in which case, the library will assume that there are no dataset-specific settings for this filter. The \Emph{set local} callback function must return a non-negative value on success and a negative value for an error. The \Emph{filter operation} callback function, defining the filter's operation on the data, is defined as follows: \snippet this H5Z_func_t_snip The parameters \c flags, \c cd_nelmts, and \c cd_values are the same as for the function H5Pset_filter(). The one exception is that an additional flag, #H5Z_FLAG_REVERSE, is set when the filter is called as part of the input pipeline. The parameter \c buf points to the input buffer which has a size of \c buf_size bytes, \c nbytes of which are valid data. The filter should perform the transformation in place if possible. If the transformation cannot be done in place, then the filter should allocate a new buffer and assign it to \c buf, assigning the allocated size of that buffer to \c buf_size. The old buffer should be freed by the filter. Some care must be taken with the functions that allocate and free memory. Standard C library functions like malloc(3) and free(3) will work in many cases, but if there is a mismatch between the memory allocators used in the library and any filter that reallocates a buffer, there could be problems. This is most often the case with Windows and/or when debugging memory allocators are being used. In both cases, the "state" of the memory allocator lies in different libraries and will get corrupted if you allocate in one library and free in another. Windows adds the C standard library via dlls that can vary with Visual Studio version and debug vs. release builds. Static links to the MSVC CRT can also introduce a new memory allocator state. The library does provide H5allocate_memory() and H5free_memory() functions that will use the library's allocation and free functions, however using these functions will require linking your filter to a particular version of the library, which may be inconvenient. If successful, the \Emph{filter operation} callback function returns the number of valid bytes of data contained in \c buf. In the case of failure, the return value is 0 (zero) and all pointer arguments are left unchanged.

\ingroup H5Z \brief Unregisters a filter.

Parameters:

id - [in] Identifier of the filter to be unregistered.

Returns:

\herr_t \details H5Zunregister() unregisters the filter specified in \p id. \details This function first iterates through all opened datasets and groups. If an open object that uses this filter is found, the function will fail with a message indicating that an object using the filter is still open. All open files are then flushed to make sure that all cached data that may use this filter are written out. If the application is a parallel program, all processes that participate in collective data writing should call this function to ensure that all data is flushed. After a call to H5Zunregister(), the filter specified in filter will no longer be available to the application.
